Sorry, Ill try to be more clear. I can see the ICMP request packets in the Linux TUN when sniffing. When sniffing the external linux interface, I see UDP packets egressing at the same rate as the ICMP requests. I expect that from this, and the logs, these UDP packets are the encapsulated ICMP requests. These packets appear to be being successfully decrypted by the XP host from the XP logs. However when sniffing on the XP TUN interface, I see nothing. Any ideas? Thx Brad -----Original Message----- From: Aaron P.

You won't be able to see the raw ping packets because they are now encrypted in the vpn tunnel...everything will look like it's part of the tunnel, which is what you want.
