No. With 2.2 kernels we used to patch the sources with grsecurity patch(es?) for PPTP NAT. > Is there any tcpdump expression to watch specific pptp traffic ? I guess you looking for something like this one: tcpdump -i eth0 proto 47 -nl > any suggestions are welcome ! thanx ! I noticed the following problem with PPTP NAT on 2.4 kernels When I route PPTP traffic to another outgoing interface and switch NAT to different source ip I had to wait a timeout to expire to get PPTP traffic NATed properly. Hope this helps, Nicholay
