telnet timeout 10

ssh 172.17.0.0 255.255.0.0 Inside

ssh timeout 60

ssh version 1

console timeout 0

do you have AAA server group LOCAL configured? if so add this statement.

aaa authentication telnet console LOCAL

make sure you do not have in your config any icmp deny acl towards inside interface, for example icmp deny any inside will block pings on inside interface, check that.

once you vpn try telnet to asa, if not success please post sanitized config.

Below is the attached config and we checked your recommendation, did'nt help us.

Thanks

sorry for late reply..

your ra vpn network is consider inside not outside, you will not be able to telnet or icmp to asa inside while in vpn and this statement pointing to oustide interface. please correct this and post your results.

remove this statement

no telnet 10.17.70.0 255.255.255.0 Outside

and replace it with

telnet 10.17.70.0 255.255.255.0 inside

No. Did'nt work............... Any other suggestions.......................

Murali

What does your logs indicate when you try icmp or telnet to inside interface while in vpn , can you post asa log output.

Jorge Rodriguez

The log file does not have any info on ICMP, we have also tried "debug icmp" still no sign ICMP packets. Besides issue with Telnet, we can't get to websites that are on our business partner "lacounty" interface.

are the websites under the 192.168.1.0 network ? f so can you reach 0.0.0.1 next hop router from the asa? when you say you cannot reach websites via lacounty interface is it through vpn or anyone behind asa.

Jorge Rodriguez

The unreachable websites are in 10.2.0.0 which resides beyond "lacounty" interface and we have this problem only when we're in VPN.

Jorge,

We found 2 issues with the config that prevent us from Telnet to the ASA.

1- Typo on nonatdmz access-list, should have

been 10.17.70.0 instead of 10.16.70.0

2- Splittunel acess-list did not include

10.0.0.2 "Inside" interface

You help is greatly appreciated,

So you guys are all set then, did you make the corrections on the acls? can you post updated config.
