static routes - PIX outside address

Similar Questions

• PIX 515 - deleting static routes

  We all have a few static routes that we change the IP addresses on. We emit static (inside, outside) order No., but seems we have to reboot the pix after the change is made so that it can use the new static IP route to the external interface. Y at - it a command that does it, so we do not have to restart the pix?

• Several public address on a Pix outside interface spaces

  I currently have a pix (6.3) with the external interface configured as part of a public ip address space of 27 bits. We are running out of addresses and need to buy another beach. Can I make this work using the pix existing and without alteration of the existing range in use? Basically, can I get a new address to my existing pix space and configure static for this space, even if the interface is assigned an ip address on another beach?

  YES, you can do quite easily.

  Example: your external interface is

  129.174.1.1/27. Now, you want to add another

  141.141.141.0/24 to your external interface.

  Is this correct?

  The technique is to use the Routing IP NAT Pool.

  In this example, you add a static route

  on the router upstream like this:

  IP route 141.141.141.0 255.255.255.0 129.174.1.1

  Now you can make static on the pix as NAT

  this:

  static (i, o) 141.141.141.0 192.168.1.0 netmask 255.255.255.0

  Easy right?

• Add a static route to a RV042

  I have configured the RV042 dual WAN port for backup smart link connected to two different ISPS.  The subnet behind this is 192.168.2.xxx.  I have a second router linksys Garland with the 192.168.2.250 WAN port and subnet behind it is 192.168.20.xxx.  My problem is that I have a not able to route traffic fron 192.168.2.xxx to 192.168.20.xxx.  How can I add a static route so that clients on 192.168.2.xxx can access resources on 192.168.20.xxx?

  1. the second Linksys router must be changed of gateway (active NAT) in router mode (NAT disabled) mode. With NAT the LAN behind the second Linksys will be not accessible from the outside unless you configure port forwarding.

  2. on the RV042 set up a static route for the subnet 192.168.20.0/255.255.255.0 to the gateway IP address 1921.68.2.250 on the LAN interface.

  3. Ideally, you must configure the same static route on all clients connected to the RV042. If you don't want to do this, you must configure the firewall on all clients on the RV042 accept ICMP redirect messages. This is important because otherwise all traffic from 192.168.2. * to * 192.168.20 would be sent to the RV042 and from there to the second Linksys that is unnecessary and could create a bottleneck.

• SG300-52. Prefer to send traffic to the default gateway rather than static route? Network stops if I disable ICMP redirects.

  I have 4 switches, each act as their own with a 26 subnet mask. They have static routes for every other switch. The firewall has a static route to each switch. If I unplug the LAN of the Firewall interface, traffic stops the flow of the switches. If I block the side LAN firewall, ICMP redirects, traffic stalls outside.

  So if you are connected to this switch, say that you pull an ip address of 192.168.122.20. Your front door is the 192.168.122.62 switch. If you try to access a server 192.168.127.142, the SG300 sends your traffic to 192.168.127.254 to get an ICMP redirect, rather than simply to communicate directly with 192.168.127.50.

  My network 'basic' is 192.168.127.0/24 vlan1 and the firewall is 192.168.127.254

  This is the route of one of my switches table (which has 192.168.122.0/26 and ports run on vlan122)

   Maximum Parallel Paths: 1 (1 after reset) IP Forwarding: enabled Codes: > - best, C - connected, S - static S 0.0.0.0/0 [1/1] via 192.168.127.254, 73:48:13, vlan 1 C 192.168.122.0/26 is directly connected, vlan 122 S 192.168.123.0/26 [1/1] via 192.168.127.123, 73:48:13, vlan 1 S 192.168.124.0/26 [1/1] via 192.168.127.124, 73:48:13, vlan 1 S 192.168.125.0/26 [1/1] via 192.168.127.125, 73:48:14, vlan 1 C 192.168.127.0/24 is directly connected, vlan 1 

  In any case, what gives? Why the switch would first try to send the stream to the firewall?

  EDIT: Here is the server routing table:

   [email protected]/* */:~$ ip route show default via 192.168.127.254 dev eth0 192.168.122.0/26 via 192.168.127.122 dev eth0 192.168.123.0/26 via 192.168.127.123 dev eth0 192.168.124.0/26 via 192.168.127.124 dev eth0 192.168.125.0/26 via 192.168.127.125 dev eth0 192.168.127.0/24 dev eth0 proto kernel scope link src 192.168.127.142 

  Hi Jonathan,.

  I'm sorry. I misunderstood the routing table you want to accomplish. Your concern seems relevant given that the matching rule more will be selected instead of one: page 275 http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/sf30x_sg30x/...

  ... "When the routing of traffic, the next hop is decided based on the longest match on the prefix (LPM algorithm). A destination IPv4 address might match several routes in the IPv4 static routing Table. The device uses the matching route with the higher, subnet mask that is, the longest match on the prefix. "...

  So go ahead and report it to the support team so the guys can make the laboratory, confirm it and declare additional:

• 3 interfaces and routing PIX

  Hi all

  I have a PIX 515E configured with 3 interfaces, exterior, Interior and a Tunnel interface to my VPN clients. VPN clients not only access within the network, I have to move them to other networks through the external interface. As you cannot route the IPSEC packets from the same interface its entry, which is why I used a separate interface for VPN clients. Default gateway is set to the external interface. Now the problem is that when the vpn users try to connect to Internet, Tunnel interface is getting traffic but does not send back as default route traffic is defined on the external interface.

  Tunnel interface is 192.168.32.253 and if I connect from a pc with the ip address of 192.168.32.50, its works perfectly fine and also routing traffic to other networks through outside as PIX knows where to forward packets. Can someone please help me solve this problem of routing in PIX.

  the Interior is 192.168.33.254 security 0

  the outside is 192.168.34.254 security 100

  The tunnel is 192.168.32.253 security 90

  NAT (inside) - 0 110 access list

  access-list 110 permit ip 192.168.33.0 255.255.255.0 any

  Thanks in advance.

  KAZ

  Unless you know that networks, clients must connect to it may not be a solution, given that it looks like you need the default routes two, one for traffic encrypted clients and the other for traffic not encrypted Internet. You may be able to create a NAT pool in the router that provides Internet access to the Tunnel interface so that all incoming client traffic is coordinated in this router to an address from a pool. That would make all remote clients look like they came from a subnet, so you wouldn't need a default route on the interface of Tunnel in the PIX. You will probably need to do this router's Internet interface an interface 'ip nat inside' because I don't think that IOS supports dynamic NAT pools with 'ip nat outside source. It sounds backwards, but I think it would work. You'll probably also want to use an access list or with the pool route map, NAT to only apply to the traffic to the Tunnel from PIX interface (i.e. VPN traffic), as I'm assuming that the same router provides Internet connectivity for the interfaces from the outside and the Tunnel to the PIX.

  Good luck!

• Next hop for the static route on the VPN site to site ASA?

  Hi all

  I would be grateful if someone could help me with my problem ASA/misunderstanding. I have a VPN site-to site on a SAA. I want to add a floating static route to point to the VPN on the ASA. Note that the traffic in this way is not with in subnets cryptographic ACL that is used to bring up the VPN. This VPN is used only as a backup.

  The static route with the next hop add local public address or the remote public address of the VPN? The next break maybe local ASA isp internet facing interface? I intend to do on the ASDM. I'm sorry if it's a simple question but I found no material that explains this?

  Concerning

  Ahh, ok, makes sense.

  The next hop should be the next jump to the interface that ends the VPN connection, essentially the same as your Internet connection / outside the next hop interface.

  Example of topology:

  Site B (outside interface - 1.1.1.1) - (next hop: 1.1.1.2) Internet

  The static route must tell:

  outdoor 10.2.2.2 255.255.255.255 1.1.1.2 200

  I hope this helps.

• Add Static route on ESXi 5.5!

  Hello

  I am trying to add a static route in the esxi using the command 'esxcli ip route ipv4 network add x.x.x.x - n x.x.x.x/xx g '. When I run this command a static route is created and applied to vmkernel port group by default vmk0. I want the static route applied to vmk3 instead of vmk0. Please me tips on how to do it.

  Thank you

  TA.

  Hi Sai,

  It's easy :-)

  vmk3: 10.28.184.8

  iSCSI target: 10.28.184.10

  vmk3 and your iSCSI target IP address are in the same subnet, so there is no need for any gateway, by default or not, or for routing.  The IP addresses in the same subnet can speak throughout the day without leaving the subnet or involving communication via a gateway.

  Yes, all vmkernel ports assumes that the default gateway of the vmkernel, but vmkernel ports other management port management is generally useless to speak in the first place outside their own subnet.

  Some examples of use of vmkernel ports case how they communicate generally:

  NFS - should speak only within its own subnet

  iSCSI - should speak only within its own subnet

  vMotion - should speak only within its own subnet

  Fault tolerance - should speak only within its own subnet

  vSphere replication - can talk within its own subnet, perhaps one VLAN stretched if in different sites, otherwise a static route can be configured

  I missed everything vmkernel port types?  I think that all down for the most part.

• Static routing question

  I just took a WRT610N and configure a few static routes for my network.

  I have the router connected to a cable modem WAN and the interface of local network connected to my LAN via 192.168.0.1.

  I have three other LAN subnets in a test environment, they are:-

  172.16.0.0/24

  172.16.100.0/24

  172.16.200.0/24

  I tried to add the following to the first subnet:

  Destination = 172.16.0.0 LAN IP address

  Subnet mask = 255.255.255.0

  Gateway = 172.16.0.1

  Interface = LAN

  No matter what I try, I get a message saying route static invalid, and I can't get anything to stick.  Everyone can't see what I'm doing wrong?

  Thank you guys!

  Gary

  The IP address of the gateway in a static route is the IP address of the connected device directly on each side of the router, either on the ethernet LAN or WAN side.

  In particular you cannot route a subnet of an IP address of the gateway inside the target IP subnet. The static route example you deposited directions where to send traffic destined to 172.16.0.0/255.255.255.0. It is impossible to set the address of the gateway as 172.16.0.1 because the router doesn't know where to send the traffic to 172.16.0.1.

  In other words, the IP address of the gateway must in most cases be a 192.168.0. * IP address that you use these IP addresses in the local network of the WRT. The IP address of the gateway should be the IP address of the router on the subnet specific target within your local network.

  For example, if your second router with address 172.16.0.1/255.255.255.0 IP LAN has an IP 192.168.0.2, then the 192.168.0.2 is the IP address of the gateway for the static route to 172.16.0.0/255.255.255.0.

• Remove the static route by default

  Hello

  I have a switch L3 which has a static default route pointing to a FW that is connected to a circuit of the Internet. The same L3 switch made EIGRP routers on our MPLS network. If this default static route disappears EIGRP will inject a default route, and users will receive their Internet traffic through the MPLS cloud as a backup.

  My question is how to remove this static road by default with a mechanism that is unique on the Internet circuit. I can't count on line protocol because it almost never goes down. I can't rely on Internet ping IP SLA addresses because if they descended through the Internet channel available on the circuits quickly and create a loop of the SLA of intellectual property.

  I wish I could do BGP with the Internet provider but this circuit is in a country where it would be difficult.

  Any ideas on how to remove this default static route based on something that is unique to this tour of the Internet.

  Thank you

  P.

  "I can't rely on Internet addresses ping IP SLA because if they descended through the Internet channel available on the circuits quickly and create a loop IP SLA."

  To remedy this situation, you must add a route with the 'permanent' switch at the end of any IP you track on your IPSLA... In this way, if this interface is down, your ping IPSLA would stop and IPSLA would be the move and change your default route.

  Example:

  Route IP 1.1.1.1 255.255.255.255 2.2.2.2 Permanent

  where 1.1.1.1 is the IP address, you are followed and 2.2.2.2 is your 'usual' default gateway

• By default static route with recevied BGP default route

  Hi guys;

  I have a problem and I don't know how to find or solve it.

  My chart is attached, please check everything first.

  Secondly, I have a multihomed BGP with two Internet service providers, I received two ISPS via BGP default route.

  Now, I have two types of IP addresses as follows:

  1 - my own prifixes, who has recorded with my ACE

  2 - iPs purchased ISP2.

  I have two networks, the first will contain my own prefixes and second will contain my prifixes ISP2. so I have to go on the internet, static route by default to the ISP2 need and that's fine, now the problem that carry the second defect I received two ISPS in routing however my table if I show ip bgp I see that I received it, but because of favorite and distancing China he disappear the default road statistics.

  so now a network is already online and the second network that contain my own IPs is out of service, of course this second network I need to routed to my isps1 via bgp and when isps1 down, go through ISP2 and I do using weight and as path prefix.

  Thank you

  Hi Nathan,

  With ACB option, you config-route map is your own prefix and set its next hop ISP 1 and 2 PSI when ISP 1 IP is not accessible. Apply the road map to interface with Network1. ACB is processed before routing.

  With option VRF, put the Network1 interface and isps1 VRF1, so it will have separate routing table. Under the vrf1 you static default config with higher AD and the next hop pointing to ISP2 in the global routing table. This will be used when you lose by default isps1. Because separate ridges VRF table routing, so netwoek1 will use the default route in vrf1 to isps1 as primary, the Network2 use ISP2.

  you use the subnet mask different than the one you used. According to the route table entry mask is 29

  Try this,

  See the race | include the ip route

  Copy the static route statement and paste this what with 'no' in the global configuration and check the routing table.

• Static route ISA570W to Comcast gateway/modem

  In my view, that it is a question of static route.

  I want to be able to connect to the gateway/Modem Comcast (10.1.10.1) using any computer on my network. Currently, I am unable to do this, I am also unable to ping the unit of Comcast. Here's my setup.

  Comcast device (SMC8014)

  WAN IP: 50.x.x.238

  LAN IP: 10.1.10.1 (255.255.255.0)

  A single cable CAT5E for:

  ISA570W (WAN Port) - (basic out-of-the-box configuration, 1 - WAN, DMZ - 1, 8 - LAN Ports)

  WAN STATIC Port info:

  IP WAN: 50.x.x.233 bridge (255.255.254.0): 50.x.x.238

  LAN IP: 10.1.10.2 (255.255.255.0)

  DHCP enabled for bridge VLAN-1 (10.1.10.30 - 99) by default: 10.1.10.2

  A single cable CAT5E for:

  Cisco SG200 - 50 p (POE switch to serve as a connection for phones and desktop computers)

  LAN IP: 10.1.10.3 (255.255.255.0)

  For devices on my network to get an IP address from the device of the ISA, ISA is also the default gateway. I have logged on to the device of Comcast and all firewall rules and blocking are disabled.

  Here's a copy of my current routing table according to the ISA570:

  Destination address	Subnet address	Entry door	Flags *.	Metric	Interface
  192.168.3.0	255.255.255.0	0.0.0.0	U	0	DMZ

  My desktop (10.1.10.32), so I'm unable to ping or you connect the unit to comcast to 10.1.10.1.

  So according to me, that missing me something simple here, it is a solution of static route, or I'm looking for policies of NAT?

  Thanks for your help and please let me know if you need more information on my network.

  -Matthew-

  OK, a few possibilities here.

  1. Did you go through this process for the SMC8014 Bridge mode?
     • http://www.handymanhowto.com/2011/08/19/how-to-configure-a-Comcast-business-class-static-IP-address/
  2. I advise to use a different subnet on the LAN of the ISA to the 10.1.10.x interface.  The reason is that when you send a request from a subnet of 10.1.10.x behind the ISA to a subnet of 10.1.10.x, your PC and the ISA assumes that the device is on the same network and will not try to route.  Consider using the subnet of 192.168.75.x by default on ISA LAN interface.

  If you do not step 1 above, then I'm fairly certain that you will not be able to browse the internet at all.  If you can browse the internet, but just can't get the Comcast router 10.1.10.1, then chances are 1 step has already been completed.

• Adding static route to the ACS

  How can I add a static route to my device SE ACS?

  I try to get AAA works on a Cisco 871 is an end of distance of a vpn s2s ASA to 871. On the router, I use as the source for Ganymede interface vlan1.

  My ACS server is on the subnet for my ASA management, but the GBA to the Remote LAN road is via its default gateway and interface from the INSIDE of the SAA. I need to get the traffic of Ganymede ACS to return through the management interface of ASA.

  Thanks in advance.

  John,

  There is no way to set a static route in the GBA unit. The only network settings, you can set are the ip address/subnet, default gateway and dns servers.

• Explain SGE2000/P static routing (equal to L2 +)?

  L2 + mean?  I know these aren't L3 switches with IVR capabilities, then what is the purpose to configure static routes, if there is no functionality InterVLAN routing?

  T.I.A.,

  Chris

  Welcome to Cisco Community!

  With get them into a huge discussion, I will try to respond as quickly and directly as possible.

  Our EMS and EMS in the series switches are layer 3 switches (can also be configured as L2) so that they are able to operate as a (inter VLAN) router or gateway for all the VLANS. Once you have created the VLANS and assign an IP address, that IP address will become the GW for this VLAN. Under routing, you will not see any scholarly networks until what you assign the VLAN to a port and the port is enabled. You will then need to configure a default route to send traffic to the cloud. The router must belong to the same VLAN on the switch. So if the switch has an IP address of 172.16.30.1/24, the router will have an IP address of 172.16.30.254/24 for example. The road reads: next hop metric 172.16.30.254 0.0.0.0/0 2 (or higher).

  With respect to the static routes as a switch L2 or L3, that they would be useful when you have a device connected to another switch that is disjoint from your typical network of the local switch. In other words, let's say you have 3 (except default native VLAN 1) VLAN V10 - 30. Everything you devices belong to these VLANs, but you have a server on 30 VLAN that is not connected to this switch. You will then create a static route for the IP address of this server to the remote switch.

  VLAN30: 172.16.30.1 (local EMS)

  Server: 172.16.30.200 (on the remote switch)

  Remote switch: 192.168.20.1 (distance EMS)

  VLAN30: 172.16.30.2 (on the EMS distance)

  Static route:

  hop metric 172.16.30.2 next destination 172.16.30.200 2

  I hope that answers your question. These are really my favorite switches, because I find them very reliable and highly configurable. I love these things.
