Remote access vpn failed, after wan-ip change

Hi.

Router: ASA 5510

We have changed the ISP, so therefore new wan ip-addresses.

Internet works, and site-to-site vpn works, but I'm failing to localice why the remote access vpn won't work.

Any help / clue would be most graceful.

Pls share your config.

Do you use IP Address or hostname for your remote access vpn? Have you changed them to the new IP?

New Member

Re: Remote access vpn failed, after wan-ip change

Is there an easy way to get the part of the config thats of interrest, and hide all passwords etc?

We're using ip-adresses, the dns is not in use at the vpn-setup.

Have you changed the VPN Client peer to the new ISP IP Address?

On the client side, I have changed the ip-address to the asdm/vpn, yes.

Re: Remote access vpn failed, after wan-ip change

Where is it failing? Can you also send the logs from the VPN Client side.

Also, you've disabled NAT-T, can you enable it:

no crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set nat-t-disable

Re: Remote access vpn failed, after wan-ip change

At the moment I doesn't have any Windows computers, we use a "ton" of macs, so I don't have the cisco vpn client log available.

The mac and the iphone says both that the VPN-server doesn't replay. So it looks like a connectivity issue. I've triple checked the ip-address both on the iphone and the mac.

I also trid your Nat-t suggestion, with no luck. (thanks though!)

Remote access vpn failed, after wan-ip change

Hi Leif,

Try to remove and reinstall client from on of the the 'MAC or iphone' with new IP and see of that fixes the issue. This may sounds like strange, but as nothing changed (except IP) on head end, I would check from client end.

Re: Remote access vpn failed, after wan-ip change

Reinstalling the client did not help (as expected). It has to be a configuration issue / connectivity fault at the asa.
