Cisco PIX L2L VPN - Remote Site Not Accessable

[briancox86]

I have a Cisco 7200 connected to a PIX 501 using IPsec. The remote site can surf but cannot be reached from the main office.

The VPN comes up woith no problem so that is not the issue. I think it is an ACL? Basically I have 10.X addressing at the remote site and it should come across the VPN un-NATted.

Ok... I figured it out. Apparently 6.2 code is alot different from 6.3. 6.2 applies the ACL of the outside interface to the tunneled traffic and 6.3 does not. STUPID CISCO!

added the permit on the outsude interface and everything worked.

Thanks!!!
