Cisco VPN :: 5510 - ASA 8.4.(1) VPN L2L Can Only Be Established Through Default Gateway
Jun 19, 2011
We have an ASA 5510, with two internet connections. One inteded for VPN l2l and the other for general users inet access.
On asa 8.04, I configured the crypto map on inteface "VPNAccess" and a static route to the L2L remote peer through VPN internet access, the default rotue was pointing the general inet router.
We bought a new firewall with 8.4.1, and now asa only tries to initiate traffic if remote peer is on the default gateway.
It ignores more specific routes (i mean longer masks) and always tries to use default gateway, but only for VPN, if I make a trace route for that peers it uses correctly the routing table.

We have two ASA5510s, each with outside interfaces to the same two ISPs (different IP addresses within the same subnet, of course). Both ASAs allow ICMP on all (inside and outside) interfaces. One ASA's default route is to ISP-1 and the other is to ISP-2. We can ping the default gateways for both ISPs from only one ASA. From the other ASA, we can only ping the default gateway for the default route but not the other. The pings originate from an inside client, first configured with the default gateway for ASA-1, then for ASA-2. Why does this happen, how do I troubleshoot something like this and how do I fix it?

We have a 3560 switch behind a ASA 5510 at a site that we are trying to access via telnet over the internet, we find out the switch does not have a default gateway configured. So I configure the following rule on the 5510: [code] Try accessing the switch, and all is good. One of our change control steps is to identify any others are connected to the device via: [code] I see the connection and show users command return 172.16.30.15, as expected. How is it possible that address can connect to that switch.

Periodically, I drop internet everywhere around my college's campus. I'm literally four feet from a router, but it doesn't seem to matter. I'll disconnect, run troubleshooter, and I'll get the error message saying that the default gateway is not available. My college is designed for Macs, but I'm running Windows 7. My Mac colleagues do not experience problems. The computer works at home and at nearly every other wireless network I've brought it in range of. Specifically, either IBM or Dell.

I recently got a new laptop and ever since, the internet goes in and out. Most of the time it is not out long enough to display the no connectivity icon or stop music from streaming but it is noticeable. When I run the troubleshooter it says that the default gateway is unavailable. I tried manually setting the connection information but the same thing keeps happening except the troubleshooter then says that DHCP is not enabled. I've disabled every firewall I can find and updated all the drivers available. Here is my info:[CODE]

I am trying to get rid of 2 old 2651xm's and 2 2950's from my CCNA days and want to get into the ASA realm. Can I be able to use the ASA, not only as a security appliance / firewall, but also be able to write the access lists, etc, to be able to use this as my router to push packets to and from my internal LAN to the outside world? I guess I should have stated as this being the front end device to my network, just after my DSL Cable modem, that is..and being the only device. I am trying to have this as my main router /firewall solution and then I have an old Linksys router I will pipe off one of the L2 ports to have an AP for my wireless devices? Is this a real solution an ASA can provide?

i'm having problem to ping succesfully default gateway on Router1 from Router2. Basically i can: - ping from R1 the serial interface on R2 and default gateway on R2 - telnet from R1 to R2 - ping from R2 to serial link on R1, BUT I CANNOT ping default gateway from R2 to R1 Below is the photo showing topology and running configuration on both routers

We have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?

When I plug my laptop up to our modem, all i get is local access. IPconfig gives me to default gateway or dns suffix. Naturally there is no wireless. My roomates laptop runs fine wired or not and we have the same set up.Not sure what to do.

I am having issues playing certain games on my ps3. So I've been searching for solutions and I came across a video that wanted me to go to run/cmd/ipconfig. I have little knowledge of computers but I'm not sure that what my ipconfig is showing is supposed to be there. At first I googled and learned about ipv6 addresses because i found that weird but i think that checks out fine. I then googled about the weird numbers and letters in my default gateway and came up empty. Is there a reason thats there?

I have Squid proxy installed on a ubuntu box here. Currently all my PC's use my ADSL modem as their default gateway but what i wanted to do was see if it was possible to use the ubuntu box as the default gateway, and have it route through Squid to my ADSL modem.

Basically, I'm using a broadband modem, which appears to be connecting fine, with all the required lights being on. My ISP says that, from their end, everything is perfect. Even my laptop shows Local Area Network as connected.However, for some reason, I am not able to access the internet. I was able to use it till last evening, but suddenly the internet stopped working. On Google Chrome, it says that there is no DNS or something.Subsequently, when I tried to access my modem settings, it shows as 'webpage not available'. I then noticed that there is no default gateway! I was able to access it the day before, but now I can't.

I'm really not clear about default-gateway on switch command, not the function but how its works.i have 1 multilayer switch (MLS 1) that have 2 vlan within it, vlan 2 and 100. on vlan 2 i assign ip address of 192.168.1.1 and on vlan 100 is 172.16.1.254. both vlans are up. then under that multilayer switch i added 2 more MLS (MLS 2 and MLS 3), and the links of MLS 2 and 3 to MLS 1 are trunking. and both MLS 2 and 3 have a same vlan with MLS 1. that i assign an ip address on vlan 2 in MLS 2 192.168.1.2 and i set default gateway 192.168.1.1, and i do the same to MLS 3 but the ip address of vlan 2 is 192.168.1.3i already setup the routing protocol on MLS 1 so that vlan 2 could contact vlan 100. but the fact it doesnt work at all, both MLS 2 and 3 cannot contact vlan 100 eventhough that are already have default-gateway setup, is there anything wrong with the configuration ??

Why it makes problems to use a default route on a BGP-router (cisco 6500 with sup720 3bxl).Only a very few amount of hosts have that kind of problem and the 50% paket loss is only between this hosts. So another host has no loss to any of the affected hosts. looks for me like there is a problem in the CEF-table.The router has a BGP-fulltable. The gateway of last resort is only set for cases like a flapping BGP-route, so that the traffic is sent to a default next hop, because sometimes he knows a better route which isnt flapping.

Is it possible to create a site-to-site ipsec vpn (lab environment) between two 5505's (ASA IOS 8.2(5) & asdm-645-206) with the same default gateway. I.E. a back to back site-to-site VPN tunnel or do I need to deploy a router and hang each 5505 off a different interface? We have plenty of public IP's but only one default gateway to our ISP (Internet).

I have RV042 on my remote network, i have problems with VPN connection , user can connect to RV042 but only inside IPs that can ping from vpn user.Is it any way to make the traffic from Rv042 will back to RV042 . maybe with nat.. in example below 192.168.5.100 is my lan IP from my DSL dhcp, and 172.27.0.20 ip on remote, traffic not back to my pc/vpn client, what i want is to translate 192.168.5.100 to RV042 LAN ip address
1485: ICMP echo request (len 32 id 256 seq 29) 192.168.5.100 > 172.27.0.20
1486: ICMP echo reply (len 32 id 256 seq 29) 172.27.0.9 > 192.168.5.100
1487: ICMP echo request (len 32 id 256 seq 30) 192.168.5.100 > 172.27.0.20
1488: ICMP echo reply (len 32 id 256 seq 30) 172.27.0.9 > 192.168.5.100

I rdp into our server 2008 via IP. This is a router on ip 0.1, this is forwarded to my server on IP 0.3. This server was setup with DHCP default gateway of 0.1. We added a new outside connection on IP 0.2. I was talked through the changes so that internal DHCP requests went to gateway IP 0.2 but RDP still used 0.1. I plan on getting rid of 0.1.Where is the setting to change the RDP to use default gateway of 0.2?

My ISP is changing out all the ADSL routers in our area and they have blocked the Default Gateway Address, so we can not access it via Web Browser. This is frustrating because they changed our Wi-Fi password, instead of just keeping what we had like an Einstein. They said they did it because of Hackers

I've been trying to connect to the internet all day. Every time it connects, but only with limited connectivity. I run troubleshooting, but it doesn't fix the problem. Sometimes it won't have anything to report back other times it says that the default gateway is unavailable. My laptop is the only device in our home that won't connect, so I don't think it's the router.I think the router is a cisco router, there is a cisco box mounted on the ceiling with a cord leading into it (I don't have access to any buttons though)I live in an apartment building with free internet, so I'm not sure who the provider is.

I had problems connecting to my wireless internet for extended periods of time with my lease expiring almost instantly. Nobody else in my house had trouble connecting, only me. Troubleshooting the connection only showed that the default gateway was not available and failed to allow me to connect despite "fixing" the problem. I attempted the ipconfig/renew, netsh int ip reset reset.log, and netsh winsock reset catalog operations in cmd as an administrator to no avail. Finally, as a last resort, I reset my modem and that finally allowed me to connect although occasionally I would be kicked off the connection and have to restart the modem again. I would still like to know the problem and a possible solution since my friends seem to have a similar problem with their wireless internet.
ipconfig/all before resetting the modem:

I have been having some trouble with my internet for awhile now. It fine one second and than it will get really slow and eventually stop working. When I troubleshoot to see what the problem is it either gives me DNS server is not responding or default gateway is not available, sometimes it will give me both. It says it fixes the default gateway problem but it will show up again 5 minutes later.
Here is my ipconfig /all

I got a hand-me-down laptop the other day. Wireless (WLAN) works fine, but I can not connect via ethernet.
It gives the "Limited or no connectivity" message, even if the ethernet cable is unplugged (no "a cable has been unplugged" message)
The laptop is plugged in to an EWIRE modem/router. Desktop connects fine via ethernet, as does my PlayStation 3 console via wireless. So I don't think it has to do with the modem/router. It's a Compaq from 2005 or so. Windows XP Pro SP3.
System:
Microsoft Windows XP
Media Center Edition

I have a general knowledge of fixing the typical internet connection problem (obtain DNS automatically, repair connection, unplug modem for 20 seconds, etc) but I've never been this stumped before.

We have a Windows XP machine on our network that is giving us a strange problem. We have it statically configured with an IP and a default gateway address which points to a router on our network. This is the same router that nearly all of our machines point to and none of the other machines have this issue.If we open up CMD and make a ping request from an outside server (public or interal servers on other subnets) we get a 'destination host unreachable' error. We can ping the ip address of the router that is assigned as the default gateway. We can circumvent this ip address by adding a static route ('route add' from CMD) directing all traffic on the network interface to the ip of the router. Once this is done we can ping and get a response from any server both internal and external. We also tried doing a tracert (without have the static route added) to an external site by IP address. The tracert does not even show a hop for the router so it seems as if the request is never making it past the interface on the XP machine. We simply get an error saying it is unable to find the host. Interesting though it does provide us with a domain name for the ip address. So somehow it is able to reslove DNS. (We have a local DNS server on the same subnet)

As shown in the diagram below, I have a central office and two branch offices, these offices are connected by a private routing service that has no connection to the Internet, the telecommunications operator in each office installs a router with a LAN and a WAN IP and configuration of these devices cannot be changed except the LAN IP. Only the central office network that is 192.168.0.0 have a router that has internet access. Remote offices have no access to the internet, what is needed is that remote offices can access the internet using ADSL router 192.168.0.254 at the central office. There are a small devices in each remote office that must connect to the internet and do not support any configuration except IP, mask and gateway, for example you cannot add a static route. Currently the pcs at remote offices has IP communication with the server from the central office using a static route.Does the solution would be to put some VPN routers between each LAN and the operator's routers (where RT yellow star appears in the diagram) and put the hosts of the two branch offices same IP range that the central office network?
