SGE2000P - InterVLAN Routing & internet Gateway

Hi all

I read articles and discussions on the forum for a while now, as I'm collecting information before the design of any change to network or make purchases.

Currently, we have a simple network and we intend to 'upgrade' it a bit. We want to implement VLANs to separate wireless clients, Desktop + servers and infrastructure equipment form between them.

From now, we have no VLAN and no manageable. We have a RV016 that handles both Internet service providers and a 3rd party connection for branches of office service (I think they are using Frame Relay, but we know, we are not concerned because we cannot touch their devices)

The reason behind the title, pointing to the famous SGE2000P, is that my workplace is located in Argentina... and we do not have as much choice as some of you guys! Actually, I was trying to get a Cisco partner to contact me unsuccessfully. We would like to replace the with a cisco RV016 1941 (and a HWIC change card).

So, back to business... ! Assuming that we use SGE2000P switches, I thought on the definition of VLANs with 802. 1 q seven of these switches, as well as a router from Cisco 1941. I'm waiting for the 1941 to manage a balancing between the two ISPS and the 3rd party link. Now, for what is the Inter VLAN routing I would have gigabit traffic between the VLANS. It is not imperative but it would be a nice feature and appreciated, (Besides, our current system works at speeds of 10/100. I know, it's hard to believe, but it's the truth!).

so my question is...

Is it possible to use an EMS as Layer 3 to hande traffic inter VLAN mode (gigabit speed) while using the 1941 as an endpoint device to reach internet (using PAT)?

Would you suggest me to use the 1941 for Inter VLAN routing, despite the limitation (*) 10/100 and use all the EMS is in L2 mode?

(*): We need to two Internet service providers, a third link to connect to EN and finally the LAN interface. As far as I know, I'm limited to integrated into a thin WAN gigabit interfaces, am I right?

Thanks in advance!

Agustin.

Hi Agustin, the switch is able to control the traffic of inter - vlan in layer 3. The trick to make it work is to ensure the default gateway of connection of hosts to be that they are a member of the SVI.

I highly recommend that you do not use the stack of these switches feature, especially if you plan to have 7 of them. The implementation of the stack is kind of poor and can give problems of reliability especially in mode layer 3.

I think it's probably better to have the switch to handle routing more before he goes to the router, it should help the performance of the network, such that it should aggregate traffic.

You need only 1 of the EMS in mode layer 3, the rest should stay mode layer 2, unless you have a specific reason otherwise. For the performance of the network, the other 6 switches must be layer 2.

  • [SOLVED] Problem with the ACB and InterVLAN routing

    Hello.

    I have Cisco 3750 G with IOS k9 - mz.150 - 2.SE4 Service of intellectual property. In my network, I have 4 VLANs with 4 internet gateways. I have set 4 static route for each gateways and with PBR to match this static routes. If I use "set ip next-hop" all traffic goes through the specific gateway interVlan routing does not work (I need to because the customers interVlan routing in different VLANS must be), and if I use 'set ip default next-hop', I was incapable of it attributed to Vlan (road-map lan14 not supported based on routing strategies).

    Model SDM is on the road that ip Routing is enabled.

    Here is my config for 2 of these VLANS:

    interface Vlan7
    IP 192.168.7.254 255.255.255.0
    IP access-group 107 to

    access-list 114 permit udp any eq bootpc any eq bootps
    access-list 114 allow ip 192.168.14.0 0.0.0.255 any

    lan7 allowed 10 route map
    corresponds to the IP 107
    IP 192.168.70.254 jump according to the value
    !

    lan14 allowed 10 route map
    corresponds to the IP 114
    IP 192.168.140.254 jump according to the value

    !

    Where is my error in config?

    Please help me, I'm stuck here almost three weeks.

    Hello

    You have created courses 2-card to set the next hop for a portion of the traffic classified with an acl.

    If you want any other traffic manager you must create an empty instance of your roadmap

    Example:

    lan7 allowed 10 route map

    football game...

    map of route allowed lan7 20 ==> Add this instance and leave it empty. You say the switch/router that he must refrain from other traffic but nothing to apply.

    Hope that this clear.

  • Cisco SG300 / ASA 5505 intervlan routing problem

    Dear all

    I have a problem with the configuration correctly sg300 layer 3 behind the ASA 5505 switch (incl. license more security)

    The configuration is the following:

    CISCO SG300 is configured as a layer 3 switch

    VLAN native 1: 192.168.1.254, default route ip address (inside interface ASA 192.168.1.1)

    VLAN defined additional switch

    VLAN 100 with 192.168.100.0/24, default gateway 192.168.100.254

    VLAN 110 with 192.168.110.0/24, default gateway 192.168.110.254

    VLAN 120 with 172.16.0.0/16, default gateway 172.16.10.254

    Of the VLANS (100,110,120) different, I am able to connect to all devices on the other VIRTUAL local networks (with the exception of Native VLAN 1; is not the ping requests)

    From the switch cli I can ping my firewall (192.168.1.1) and all the other gateways of VLANs and vlan (VLAN1, 100, 110, 120) devices

    Asa cli I can only ping my switch (192.168.1.254) port, but no other devices in other VLAN

    My question is this. What should I change or installation in the switch configuration or asa so that other VLANs to access the Internet through the ASA. I will not use the ASA as intervlan routing device, because the switch does this for me

    I tried to change the asa int e0/1 in trunkport (uplink port switch also), to enable all the VLANS, but as soon as I do that, I can not ping 192.168.1.254 ASA cli more.

    Any help is greatly appreciated

    Concerning

    Edwin

    Hi Edwin, because the switch is layer 3, the only necessary behavior is to ensure that default gateways to the computer are set on the SVI interface connection to the switch to make sure that the switch is transfer traffic wished to the ASA.

    The configuration between the ASA and the switch must stay true by dot1q, such as the vlan all other, unidentified native VLAN tagged.

    Also, if I'm not wrong, on the SAA you must set the security level of the port to 100.

  • Help with major security problem if you please. Internet gateway?

    Hello

    After a few weeks of scratches all about untangle sceurity perceived a few questions with email etc. - yesterday I belive I discovered a big problem and need some help please.

    I hope that I write from own machine because I believe that desktop home computers are compromised.

    Main PC is running XP and has a connection via a cable ethernet via a bt Home Hub2.

    Yetsrday while watching my network connections I noticed something called "Internet GATEWAY" above my LAN icon.

    It showed that I had been connected for over 2 days (a little more than 2 hours for the LAN) even when the PC off and was send/receive many packages and seemed much faster than my LAN. problem: I click on this & it won't let me log out or see properties / settings - I get a warning about 'connection is currently unavailable '... I really worry that it is someone else on my PC - is this right? How can I fix it? and it is a matter for the Police.? I'm really worried. Other symptoms, I noticed - my windows log on 'his' dissapraed a & in the event Manager-, there is no security - only since 2006 newspaper.  Very slow PC. Running SuperAntispyware - no problem after removing a Security Center option turn off a few days ago.  Really gratfeul l to help guys. Am at my wits end. Very garteful using anyones.  I guess that my internet connection and PC was hacked/compromised.

    To be clear, you remove all networking services, but just the part that detects and controls "gateways" as your router.  This removes the "Internet gateway" of network connections icon, but should not do something else.

    If a right click or double click on the "Internet gateway" just produced a message "connection is busy", which makes me think that something is not configured correctly - either the router (bt Home Hub) has turned off UPnP (or does not really support) or the UPnP in network services service is not installed, or something else.

    I don't think that someone else is controlling your connection, but as I said, the other symptoms you describe indicate a malware problem continues and you need to take steps to ensure that your machine is free from malware.

  • "Internet gateway" - NOT a TYPING error! Is this a known Ms error?

    I connect to a wireless router, and I do not share my connection with someone else. I have a Verizon FIOS fiber internet service. After some installation of their programs running, I noticed an icon (with two computers) that appear in my taskbar, which says "Internet gateway" If hovered you over it. Sometimes he would show 'connected', but most of the time he would show "disconnected" (if she showed at all).

    Lately, he has been showing much and appearing as "connected." My performance has also suffered, I decided to look more closely at this "Internet gateway". I tried to click 'disconnect', but she would not obey. When I clicked on 'Status', a box appears showing 'Internet' (globe), 'My Computer' and "Internet Gateway" (again, no misspelling.)

    I wouldn't spend Microsoft leave a misspelling as this sucked into production (and never fix it with Service Packs or updates), but'd me also suspect that someone had created a piece of malware which resembled the Internet gateway, but who did bad things and resisted to disabled. Can someone confirm for me if it is a legitimate spelling of Microsoft error or if I should indeed suspect this process as a malware?

    Thank you

    1. you would be better to start a new thread... the fact that it is marked as 'Responded' will keep a lot of people see things.

    Uh, duhhh... What is the right way for me to do that? Do I have to ask the question again and just include a link to this post?

    Yes, this is the way to do

    2 re your post last Sunday where reference you the site practically networked - I'm not sure of the spelling, but if you see "Internet gateway" in network connections, it's just your router via UPnP, Microsoft.

    If you have a compatible router UPnP - and most are these days - and you enable UPnP in router configuration (often) utility, and you have enabled UPnP user interface, you get the "Internet gateway" icon in network connections.  You can use the icon to configure the router without using the web interface of the router.

    I don't think I have UPnP enabled for this connection. I don't see the Internet gateway in network connections. only in the system tray.

    Thanks for your help and advice, PML!

    G

    Even if you don't think you have UPnP turned on, you can be certain that it is not.  When Microsoft first introduced UPnP, several people a bit paranoid (including the FBI) said that it should be disabled on each machine.  Steve Gibson, which some might say takes such things a bit too strongly, apparently still accepts 10 years later, and has a simple utility to turn UPnP: http://www.grc.com/unpnp/unpnp.htm

  • Internet gateway

    Hi I have just re installed xp family after a motherboard failure. I use a linksys modem and their router WRT 54 G V5. When connected I notice above the normal LAn connections an internet gateway icon showing it is enabled. There is no info about it just says its connected. When I connect a laptop to the router with an ethernet cable, it shows in the connections but is disabled. Is it normal to have this connected gateway when I use my PC (that is to say is - this icon router) or should I worry that the person who installed my motherboard has access to my PC?

    assistance would be appreciated for this problem, I'm sure that I had no internet bridge showing when I originally installed the router

  • ASA 5505 as internet gateway (must reverse NAT)

    Hi all the Cisco guru

    I have this diet:

    Office-> Cisco 877-> Internet-> ASA 5505-> remote network

    Office network: 192.168.10.0/24

    Cisco 877 IP internal: 192.168.10.200

    Cisco 877 external IP: a.a.a.a

    ASA 5505 external IP: b.b.b.b

    ASA 5505 internal IP: 192.168.1.3 and 192.168.17.3

    Remote network: 192.168.17.0/24 and 192.168.1.0/24

    VPN tunnel is OK and more. I have the Office Access to the remote network and the remote network access to the bureau by the tunnel.

    But when I try to access the network remotely (there are 2 VLANS: management and OLD-private) to the internet, ASA answer me:

    305013 *. * NAT rules asymetrique.64.9 matched 53 for flows forward and backward; Connection for udp src OLD-Private:192.168.17.138/59949 dst WAN:*.*.64.9/53 refused due to path failure reverse that of NAT

    Ping of OLD-private interface to google result:

    Result of traceroute

    How can I fix reverse NAT and make ASA as internet gateway?

    Why you use this NAT type?

    Access extensive list ip 192.168.17.0 WAN_nat0_outbound allow 255.255.255.0 any
    NAT (OLD-private) 0-list of access WAN_nat0_outbound

    You are basically saying the ASA not NAT traffic. This private IP address range is not routed on the Internet. This traffic is destined to be sent over the Internet? If so, that LAC should then not be there.

    If you want NAT traffic to one IP public outside the ASA, you must remove this line and let the NAT and GLOBAL work:

    NAT (OLD-private) 1 0.0.0.0 0.0.0.0

    Global (WAN) 1 interface

  • Why apear internet gateways in network connections

    In Windows XP, I click on network connections and internet gateway is sometimes there and sometimes not.  Why is this?

    Thanks for any help.

    Jack

    This can occur if you do not have your own point of access to the House, but connects directly to the front door of your ISP.

    My ISP were some gateways that I see, but others which shows nothing. And as they change what bridge I use, an Internet gateway sometimes appears in my network connections.

  • LRT214 InterVLAN routing databases

    Could someone understand me, what "InterVLAN Routing" setting (under management port > 802 1 q LAN) actually did or influence?

    It's a bit tedious to find trying and the manual, which is essentially a textual serialization of interfaces Web (kind of pointless), doeosn can't help much.

    It is just a shortcut for firewall access rules, or influence it something else? I can get between the VLANS with access for people with disabilities, and appropriate rule set. However, I have however a strange behavior.

    Anyone know?

    Firewall access rules can override the settings of the inter-VALN. Without the two access rules, hosts VLAN1 will not be able to access hosts in VLAN8 and vice versa.

  • InterVLAN routing for S4810 VLT

    Hello

    I just want to clarify things because I get confused all intervlan routing if it is possible to implement if I used VIDEO Lottery devices

    First of all when I configured the VLT field in sweetheart two switches (S4810), I need to have an itinerary for my VLAN

    -what I used intervlan routing is my favorite, but when the peer routing, active in VLT intervlan routing is applicable or supported in routing peers. ?

    -also all configurations of the two peer switches must be identical or same

    • example: when I configured intervlan routing in Peer-1, also, I need to configured intervlan routing in Peer - 2

    I want to have an answer if I need intervlan or OSPF configuration with this problem

    Thank you very much

    BRENT

    This technical guide I think answer all your questions. Yes, you can have VLAN routing enabled on the switches. The guide goes through many examples, including examples of switches that is configured to perform the VIRTUAL LAN routing. It also includes examples of configuration that you can use as a reference.

    I think that Reza questions 3 and 4 are more important than questions 1 and 2, but perhaps do not go quite far enough. The two switches to assign certain ports to a vlan specific and use the vlan by default for most of the ports. There are no statements on a switch which create the vlan but only statements that a port must Access a specified VLAN

    interface FastEthernet0/1

    switchport access vlan 7

    On some versions of switches that may be enough to create the vlan, but on other switches, it is necessary to create the vlan before using it. Maybe something like

    VLAN 7

    name server_vlan

    I would ask if the VLAN on each switch existence?

    There is another question in this config. The switches have created more than 3 VLANs (vlan 1 - the vlan by default and vlan 2 and vlan 7.) But the L3 switch configured more than one interface vlan (3, 4, 5, 6, 8, 9). Without a vlan underlying pertaining to these layer 3 interfaces vlan will not work.

  • No "ip Routing" command on the switch and still intervlan routing.

    Hello

    In my companies 4500 switch I see there is intervlan routing configured for 4 VLANS there but I don't see any command "ip Routing" on this subject

    to enable routing on the switch. A switch can route the same if the command is not there?

    Ninja,

    Default configuration options often do not appear in "show run".  Please try «performance see all»

    Kind regards

  • C3750 interVLAN routing - no internet access for customer switches

    I have a stupid question with my itinerary (intervlan).

    I have a test configuration to a stack of C3750 as core and a few 2960's like access switches.

    http://users.fraeco.be/setup.png - switch at the bottom is the new network (VLANNED). The switches on the left is the current network of production (10.1.1.0/24)

    The C3750 to the router is a 30 network.

    There will be 6 VLAN but at the moment I have one configured. VLAN50 - 10.5.1.0/24

    The C3750 I can ping my network current production, internet, other VLANs in the testsetup... Everything.

    Of the C2960 I can ping other VLAN, join the entry door, reach the router, reached the currenct production network. But I can't reach internet. I have configured 'ip default-gateway 10.5.1.254' on the C2960. C3750 relevant config is down below.

    How can I reach other networks connected to the router and the internet not switches to access? I'm trying just to ping 8.8.8.8.

    Hi, Maxim,.

    I have no idea about your configuration exactly but for the account information that u as far as I can tell... Configure all the respective host to its ip address vlan respective gateway.

    There should be a static route pointing to the router on the switch of the MLS.

    And also, make sure that it should be static (or entered dynamic in case you use PGI) of all subnets of VLANs pointing to the ip directly connected inverter MLS.

    It will certainly work.

    Thank you

  • Route Internet traffic against the default VPN on SAA route

    I want to transfer all internet traffic to a VPN connection via the internal network and not divided the digging of tunnels or direct connection to the internet from the OUTSIDE interface.

    I have a VPN connection default gateway, so all traffic is pushed back on the OUTSIDE interface when the VPN is in place and the user connects to the Internet.

    Is it possible to send Internet traffic to the INSIDE interface, internal network, to route to the Internet.

    I'm not looking for another solution, it's the design, I would like to implement.

    As always, any help is greatly appreciated.

    Of course you can, simply set the following text:

    Route inside 0.0.0.0 0.0.0.0 in tunnel

    The foregoing will force all VPN traffic after be decrypted to the next break of the SAA within the interface defined above
