VPN Client 3.5 through ICS to PIX515

Greetings,

A customer of mine is trying to run a Cisco VPN Client 3.5.1 from behind Microsoft ICS (on Win98SE).

They claim to be having problems with it, even with the IPSec over NAT option turned on (client side)... Don't know yet if they have it turned on for the connection group on the PIX.

Anyone who has "been-there-done-that", able to provide me with the common problems?

Thanks!

Darren

Re: VPN Client 3.5 through ICS to PIX515

I am having the same problem with a couple of my users. It appears that when Win98 nat's the packet it changes the source port as opposed to leaving it port 500. Then when the pix responds to port 500 the 98 box sends an ICMP unreachable. I am theorizing that you should be able to forward port 500 on the 98 box to the internal box, but this is often not very practical. Has anyone else had any better luck.
