VPN passthrough w/ PIX 6.3(5)-No data received

I recently swapped out a DD WRT gateway/router with a PIX 501, and now I can not connect to the VPN at work (asa 5510) with the Cisco VPN client.

I was able to connect before no problem, the PIX connects to a SBC dsl modem. Bytes in is zero, however bytes out goes up. I am able to log in just fine, I get an IP address, and seem to be connected.

Any help would be much appriacheated, this problem is driving me nuts!

my config:

interface ethernet0 10full

nameif ethernet0 outside security0

nameif ethernet1 inside security100

Re: VPN passthrough w/ PIX 6.3(5)-No data received


You could do either of 2 things.

1) Enable NAT-Traversal on your ASA

2) Add the following on your pix :

fixup protocol esp-ike

This allows one IPSEC connection to run through PAT.
