  nat problem?

  Vuze download is very slow... He pointed out that I have a nat problem... Help please.?

  Hello

  ·        What browser do you use to access the internet?

  ·        What is the full error message that you receive?

  ·        Is it only when you download on Vuze?

  I suggest that temporarily disable you antivirus software and firewall installed on your computer and check to see if it helps:

  Disable the anti-virus software

  http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

  Enable or disable Windows Firewall
   http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off

  Note: disabling anti-virus or Windows Firewall can make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

  You can also post your query on Vuze forum to get help:

• NAT problem

  Hi Experts,

  One of my office have Cisco ASA 5510 with ios 8.4 (5). Everything is configured and works very well except the static NAT. I have a public IP block, I used to set up static NAT.  The internal server that is configured with the static NAT does not receive internet or anything. When I removed the static NAT, the internet is to learn (with the WAN IP interface). The server is placed in the DMZ. I left the server but it does not work.

  Kind regards

  MARTIN

  Hello

  In your case the configuration format static NAT for the server would be

  network of the object

  This would bind the local IP address of the public IP configured on the command "nat" . This means that outgoing connections would also use this public IP address. If you had a static configuration similar PAT already then you wouldn't really need that UNLESS you change the mapped/local port in the "nat" command.

  But set up static NAT would mean already that he would cancel the PAT Dynamics for outbound connections from this server. Naturally, there is a small chance according to your current configuration of NAT complete even this static NAT can be overridden, but I doubt it. If the above "packet - trace" is intended for the DMZ server in question then there should be no problem.

• LAN to LAN PAT/NAT 3020 hub

  I have a client who wants to create a tunnel L2L, but said that they will only allow us to use up to three IP addresses. I never had no other customers ask me to do it this way and I'm a little confused as how I should make it work. I'm guessing that a form any NAT/Pat should solve the problem for me. Could someone please point me in the right direction.

  Thank you!

  Yes, you can use this approach to NAT. Maybe they're "too cautious" with their security.

• ASA 8.3 - SSL VPN - NAT problem

  Need help to find how to configure anyconnect VPN with VPN client using a NAT networking internal.

  There are many items on the side - how to disable NAT for vpn pool.

  I need to create the gateway VPN to the complex international lnetwork, vpnpool is out of range of regular subnet of that network, so it's going to be questions witout NAT routing.

  I so need to vpn clients connected to be PATed to . The problem is that there is also a dynamic to PAT rule for the ordinary acccess Iternet which translates as 'rules NAT asymmetry... "error.

  Create two times different NAT rules and moving them on up/down makes no difference. There are also some hidden rules of vpn setup :-(that could not be seen.

  V8.3 seems is destroying trust in Cisco firewall...

  Thank you.

  Stan,

  Something like this works for me.

  192.168.0.0/24---routeur--172.16.0.0/24 ASA-= cloud = host. (the tunnel he get IP address of 'over' pool, which is also connected to the inside)

  If I get your drift... bypass inside and outside is not really necessary on Cisco equipment as it should work straight out of the box via the proxy arp, but I'm not face or solution providers for remote access.

• PAT/NAT and VPN through a PIX

  "PPTP through the PIX with Port address translation (PAT) does not work because there is no concept of ports in GRE"-this is an excerpt from a config PIX version 6.2 and below.

  1. how this problem has been fixed in 6.3? GRE is encapsulated in udp or tcp to use ports to follow the connection?

  2. is it "fixup protocol esp-ike" use the same technology - the source port created by the IKE protocol? -ISAKMP cannot be enabled when you use this command

  3. What is "isakmp nat-traversal? How is this different from fixup protocol esp-ike"

  Thank you

  RJ

  1. when the PIX sees outgoing PPTP (TCP 1723 port) packets it now opens holes for them to return, as well as opening a hole for the GRE packets, it has never done this before. The PPTP TCP packets can be PAT would be fine because they are TCP packets. GRE packets, I believe, are followed by the id field only tunnel in the package.

  2. we use the source port of the ISAKMP packet for ESP packets as well. The current limitation is that if you have this option, you cannot use the PIX to close the IPSec sessions, so you can not turn on ISAKMP any interface. You can also have only a single IPSec client internal to use this feature.

  3 NAT - T is a new standard for IPSec to work through a NAT device peers, because they detect changes of address during the negotiation of tunnel and automatically encapsulate packets in UDP 4500. This market allows the PIX and the other device (if it supports it) to automatically detect a NAT/PAT device between them. This differs from the "esp - ike correction '' that the PIX ends not in fact the IPSec tunnel with esp - ike, but it is the endpoint in nat - t.

• ASA IPSEC site-to-site with NAT problem

  Hello

  I have what I thought was a simple configuration, but I saw the questions and could use a second set of eyes.

  I have a site-to-site between two locations:

  Site A is 192.168.0.0/24

  Site B is 192.168.4.0/24

  I was requested to NAT all communications between these sites for 10.57.4.0/24 and for a single static 192.168.0.112 NAT host at 10.57.4.50.

  Tunnel is running, and I can ping through the link at the end to 192.168.4.20 host; no problems.   But I'm having a problem application where it will be established communications.  I suspect it's the reverse NAT, but I went through the configuration several times.   All NAT connections would be 10.57.4.50 address should given to 192.168.0.112, no restrictions.    All connections to 192.168.4.20, should be NAT should 10.57.4.50 to transverse tunnel.

  The system of site B can also ping 10.57.4.50.

  Here's the running configuration:

• Open with a Xbox NAT problems.

  When I got my 1900ac I used Media Priortization to get NAT open for Call of Duty Advanced Warfare on my Xbox One. prioritize the Xbox. It worked fine for about 6 months until what I changed my operator of cable/net of Nextech in Ks. This company uses the 1900ac to connect its system to all it's customers (since I already had one they use mine). Unfortunately, I am unable to get an open NAT in this game I tried almost everything, NAT forwarding, triggering, prioritization of the media. Support of NexTech & Xbox Live support, useless. I tried Portforward. com, nothing. Redirect port 53 breaks the connection to the network & making the static ip address change for Xbox has not helped. Almost everything I looked at seem obsolete & I am at my wits end. It would seem by now Linksys should have available solutions, any ideas?

  Chin_pamz13 thank you very much for your answer. I tried to check if my modem had a public or private ip address, but I don't know how to do this; I read on double NAT elsewhere. Nevertheless, I think I finally found a solution that seems to work so far. I went to the website "tech - recipes.» com "& found an article, 'Xbox one open NAT' by Aaron St. Clair.» I tried his first suggestion regarding the port of release, with additional ports I had'nt seen before. Who has not worked for me so I followed his instructions to the Xbox in the demilitarized zone & it works! I think that my problems from before were the result of bad to configure the static ip address for my router & Xbox. The previous instructions had me change the ip in the console with the router. Aaron said does not do in the Xbox, leave the router to do the work, it's supposed to do & make sure the console settings are on automatic. In the router in the DMZ, I was'nt sure how to proceed, but at the bottom is a section called list of reservations DHCP; clicked on this, XboxOne saw, clicked on that & he filled the top for me MAC address. Then I went to network settings Xbox, advanced & clicked settings on "automatic" to the ip address, subnet and DNS. I checked the connections mutiplayer, toured "hold bumper & trigger buttons" & finally got a NAT open; pulled up to cod Advanced Warfare & also got open NAT it. I could have screwed up when I did the port triggering, but given the difficulty of the DMZ seems to work I'll let things alone. Hope this helps anyone else having problems NAT open.

  MTU: tried 1365 and 1452, currently on 1452

  UPnP: off

  NAT: on

  Port Range Forwarding - (tried reccomendations cisco and xbox, tried the verses of individual ports this range, currently at)

  (looked in the outbreak, but as I have 2 devices, if I let a range of open ports, I want that it does match the xbox)

  Application: xbox

  Start port: 53

  End port: 3074

  Protocol: the two

  IP address: 192.168.1.20

  Xbox is set to:

  IP: 192.168.1.20

  Subnet mask: 255.255.255.0

  Gateway: 192.168.1.1

  DNS: automatic

  reading only 1 dns (see notes)

  Notes:

  router port range is 100-149, so DHCP should not be a problem (I guess) if ip xbox is put out of reach ([192.168.1.20] being 20)

  In my status tab in the router, it gives me only a dns. When I look at online modem, it gives 2 different DNS.

  Each time, I have everything works a turn at a time, the computer always connects, Xbox Live still connects, but he still has the problem of nat.

  I don't think it's a matter of double nat, bc when I look at the stats of my modem there is nowhere to configure ports (seems to be the modem only 1 Ethernet only)

  Also, I noticed that the mtu of my modem is 1500 (I changed the mtu on the router, but not the mtu of my modem [it only allows me to change the mtu of my modem])

  Help, please. I've been dealing with it and try different combinations of ports and options for 4-5 hours now. I'm starting to crack: S :).

  Well, I found my own solution.  I looked at all options as what could be easier for the components to deal with.  Here's what worked:

  Computer:

  Configuration: Auto DHCP

  MTU: 1452

  UPnP: on

  NAT: on

  DMZ:

  Source: 192.168.1.100 to 100

  Destination: 192.168.1.1

  Xbox:

  I could leave it on auto dhcp mac address book bc but it looks like this:

  IP:192.168.1.100

  Subnet mask: 255.255.255.0

  Gateway: 192.168.1.1

  DNS: automatic

  Combined with a DHCP reservation [via the mac address (for the safety of the DMZ)] all of it worked.  With a DMZ, I didn't have to worry about which ports where correct.  It was just messy because I was 2 devices of connection and could not choose a single static ip address. So, the example ip ending (20) was not default range of the router of 50 numbers. Pay attention to your range of ip addresses in the router settings.

  * Make sure that your DMZ is on only a single or a partition of ip addresses, and you have other DHCP reservations for these ip addresses * you can find the mac address for xbox by accessing the network > configure network > additional settings > click Advanced settings, and not choose a 'different address', you should see a below *.

• NAT problem? Large amount of NAT translations.

  I have a client with a particular site who complains constantly of performance.

  They have a 871 at the location remote with 4 tunnels IPsec, built over WAN connections to their provider hosting the database and software.

  There are about 50 people who work at this place, but I show 3410 current connections with a peak of 14703. I don't see how that's possible with only 50 people and starts to lean towards the NAT config which can be the cause of the poor performance that users encounter.

  NAT translations, by default, remain active for a very long time. If I remember correctly, is 24 hours, but I have to what to look for to be sure. They don't take a lot of memory, so this isn't normally a problem, but if you encounter conditions that you think may be due to this, it is quite easy to limit the wait time.

   ip nat translation timeout 1800

  This will set the timeout for new connections to half an hour. Existing connections will always keep the original deadlines, then you might want to wait a period of slow to change and the issue a "clear the ip nat translation *" right then to clear existing translations.

• NAT problems

  I've implemented a Cisco ASA 5505 partially. We have access to the internet and can come out without any problem. We have a web server that is on a 2nd IP that I need NAT inside. I did previously on a pix, but for the life of me I can't make it work.

  I do not use a DMZ for that. I don't have time to re - ip to the web server on a different subnet. I just need to get this working so that the site works.

  Hi David,

  Here's how to

  public static publicIP (indoor, outdoor) webserverip netmask 255.255.255.255

  outside_access_in list access permit tcp any host publicip eq www

  Access-group outside_access_in in interface outside

  "We have a web server that is on a 2nd IP that I need NAT inside."

  If you want to say is, ' your Web server is inside the interface, but not in the same subnet with inside the IP interface ", then what you have to do is create void interfaces. Then place the name of subinterface in above static, instead "inside" and set the gateway on the Web server as void / IP of the interface

• asymmetric NAT problems

  Hello

  I have problems entering other networks out of the interfaces of the SAA.  Can I VPN in and access anything whatsoever inside interface and beyond in the kernel.  When I try and access a DMZ server off the coast of the ASA I get errors on asymmetric NAT.  Client VPN is available as an address of 10.112.15.x.

  Can anyone help?

  I enclose some of the config.

  Guidance on what I'm doing wrong?

  Thank you.

  Hello

  The reason is that you don't have a rule for traffic to DMZ sheep.

  access-list allowed dmz_nonat 10.112.6.0 255.255.255.0

  NAT (dmz) 0-list of access dmz_nonat

  This should solve your problem.

• Tunnel + static NAT problem

  Hello:

  I configured a Pix501 to establish a tunnel from site to site with a 1710 in the central site and it works fine, except for a small problem. The central site hosts a Domino server that must have an entry static nat to allow servers on the internet to deliver mail to it. So, the problem is that even though I created a road map to avoid NAT in site traffic to site, the static entry seems a priority on the road map and the mail server is always using a NAT. So the SOHO cannot access to him. What can I do to fix this?

  I need to use an entry like this:

  IP nat inside source static tcp 172.16.34.22 1352 200.212.0.66 1352

  Any help?

  Thank you

  You must do the following:

  (1) create a loopback interface with an ip subnet that you are not anywhere in your network. Leave; s 10.10.10.0/30 say:

  loop int 0

  IP 10.10.10.1 255.255.255.252

  (2) create a roadmap to match traffic from the 172.16.34.22 Server destination and from the other side of the tunnel

  access-list 101 permit ip 172.16.34.22 host 192.168.0.0 255.255.255.0

  permissible static route map 10

  corresponds to the IP 101

  set ip 10.10.10.2 jump following (some address to the loopback interface)

  (3) implementing the road map inside the interface of the router where you have the server

  inter e0/0

  Static IP policy route map

  That's all

  Hope that helps

• IPsec client for s2s NAT problem

  Hello

  We have a remote site (Paris) with a 5512 with some s2s and RA light customer vpn (anyconnect IPsec) tunnels.  AnyConnect has no problem, but the ipsec client can not pass traffic on the LAN.  The subnet behind the fw is 10.176.0.0/16 and the RA 10.172.28.0/24 customer pool.  However, we have a s2s than nat 10.0.0.0/8 tunnel and it appears that customers vpn IPSEC RA being bound traffic matches this rule and prevents connectivity to local resources via vpn ipsec client.

  This method works on other sites with almost identical configuration, but for some reason, it doesn't work here.  I can't specify different subnets for the s2s tunnel because there is too much of.  Can someone help me and tell me why I can't get this to work?

  Hello

  So you're saying that the AnyConnect is working but not IPsec? What is the the AnyConnect VPN? It is outside the 10.0.0.0/8 network?

  You should be able to substitute the NAT VPN L2L configuration by simply configuring a separate NAT for the local network for VPN pool traffic at the top of your NAT configurations

  For example

  being PARIS-LAN network

  10.176.0.0 subnet 255.255.0.0

  object netwok PARIS-VPN-POOL

  10.172.28.0 subnet 255.255.255.0

  NAT (inside, outside) 1 static source PARIS PARIS - LAN LAN destination PARIS-VPN-POOL PARIS-VPN-POOL static

  This should ensure that the first rule on the SAA is the NAT rule that matches the VPN Client for LAN traffic. Other aircraft in the L2L VPN should still hit the original NAT rule to the VPN L2L

  If this does not work then we must look closer, the configuration.

  Hope this helps
