Another PIX VPN Question 1

[jfwebber]

I have configured my PIX 515 as a terminating VPN device. I am trying to connect via my home Windows ME workstation using PPTP. I am connected to the internet via broadband connection. I am able to connect/authenticate but I am unable to ping any nodes on the inside (192.168.1.x). Here is the PIX config:

Any ideas? Thanks in advance for any assistance.

try adding...

access-list inside permit icmp any any

 

[jfwebber]

By adding access-list inside permit icmp any any, won't that allow icmp packets to pass thru the PIX from any host on the inside (192.168.1.x)?

 

[havanajoe]

The way that I read your access-lists your inside access-list is for any traffic that is starting on the inside going outbound. Your first access-list is access-list inside permit ip any any. I have analyzed it a little more and that wouldn't help you anyways because through the VPN you are already on the inside network. Have you tried adding the permit icmp any any to your vpnlist access-list?

 

[jfwebber]

I not have tried adding the permit icmp any any to my vpnlist access-list. I will give that a try. Thanks for the help.

 

[icvanstra]

Have you had any luck with this? I'm having the exact same problem....

 

[jfwebber]

I resolved the issue. The personal firewall I have running on my PC was the issue.

Thanks for all who helped.
