IOS SSL VPN problem

I am implementing a SSL VPN with IOS version 12.4(13r)T5 on a 2801 but when I try to connect to the tunnel mode with the latest svc (anyconnect-win-2.2.0133-web-deploy-k9.exe) with https://1.2.3.4/tunnel the ssl vpn client can't connect.

The error on the router is:

Jun 5 16:07:55.755: WV: Appl. processing Failed : 2

Jun 5 16:07:55.755: WV: server side not ready to send.

The following is the configuration:

Re: IOS SSL VPN problem

Is your pool in the same subnet as the inside interface?

Try to compare your configuration from the following link , maybe you are missing something?

Re: IOS SSL VPN problem

Also, I think you need to be running at least 12.4(15)Tx, to support the AnyConnect client, have a look at:

Re: IOS SSL VPN problem

Hello, config seems OK, Since your IP pool is on the same subnet as the LAN, thats also ok. Otherwise you have to create a loopback.

Anyway did you upgrade you IOS from 12.4(13r)T5 to 12.4(15)Tx ? (As mentioned in my last post). This is required for the 'new' Anyconnect client to work. You can only run the Cisco SSL VPN Client (SVC) on your IOS version.

Please re-read my last post. Regards

Farrukh

Re: IOS SSL VPN problem

Also for your Clientless context, I don't think the following will work, SSH needs special handling (like the ASA firewall has a separate plugin for this). I don't think the IOS SSL VPN supports this to date? If you got it working please let me know also :). I need it for one customer.

Re: IOS SSL VPN problem

Hi,

the IOS version on the cisco 2801 is the last: c2801-advipservicesk9-mz.124-15.T5.bin

and need to deploy only (for now) the context context-sslvpn2 (the one with Tunnel Mode-Full tunnel client mode).... but the error on the log remain.

Just a q:

if the ssl vpn client need to do a slip tunnel (connect the pool on the ssl tunnel only vs the network 10.0.0.0 /24) the following is correct ?

svc split include 10.0.0.0 255.255.255.0

Thanks again for your time.

Re: IOS SSL VPN problem

Yes, this systax seems correct, more details can be found here:

http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/htwebvpn.html#wp1354672

why don't you enable detailed debugging on the ROUTER and attach here?

debug webvpn tunnel

debug webvpn authentication

debug webvpn aaa

debug webvpn cookie

debug webvpn package

debug webvpn entry

Also one important thing, in Internet Explorer:

Tools >> Internet Options >> Advanced

Check "Use SSL 3.0" and "Use SSL 2.0"

Clear Browse Cache/Cookies

IOS SSL VPN problem

Hello,

you could try to remove the "domain clientless" extension defined in your webvpn context :

#gateway ISR2801-RM domain tunnel

I had the same issue and I believe that the domain is somehow linked to the trustpoint, so while the domain declared is not part of the selfsigned certificate defined in trustpoint, there is no need for the option domain tunnel;
