pix vpn ping issue

nrousseau

Level 1

Hello,

I got a pix 501 (6.3-4) over a lan and trying to use Cisco VPN Client (4.0.2-D) on a remote pc.

I can open a vpn session.

I can't ping from the remote pc to the lan

I can ping from any station on the lan to the remote pc

After I've made a ping from a station on the lan to the remote pc, I can ping from the remote pc to the lan.

I'm so newb, trying for 2 days modifying acls, no way.

I have to say that I'm in dynamic wan ip on the lan and on the remote pc.

Any idea about this problem ?

Any help is welcome.

Here is my pix configuration :

yes ! it works !!

many thanks.

Jay, I am having the same problem, but my PIX won't accept the isakmp nat-traversal command, I just get the information for other isakmp commands. Any ideas.

hello dianad,

you need to upgrade you PIX to the latest IOS.. try uploading it to 6.3 (3) or 6.3 (4). it isnt supported on the older IOS. try it and let us know..

All the best..
