Subject: NATing PPTP GRE traffic
Date: Tue, 20 Jan 2004 09:11:38 -0500 [thread overview]
Message-ID: <00b901c3df5f$52597f30$686fa8c0@vincent> (raw)
I have been try to setup a firewall that will pass PPTP/L2TP traffic to a
windows 2003 server inside the network...
I am using Mandrake 9.2 with the 2.4.22-10mdksecure (delivered) kernel.
I believe that I have shorewall configured correctly rules below:
DNAT:info net loc:192.168.105.1 tcp 1701 -
DNAT:info net loc:192.168.105.1 udp 1701 -
DNAT:info net loc:192.168.105.1 tcp 1723 -
DNAT:info net loc:192.168.105.1 47 - -
and I am loading the following netfilter modules for natting pptp:
ip_nat_pptp
ip_conntrack_pptp
ip_nat_proto_gre
ip_conntrack_proto_gre
The issue I am having is the when I try to VPN in to the nated windows
server things seem to go ok for the initial communication but I get the
error below:
protocol 47 unreachable [tos 0xc0]
After this occurs a half dozen times the vpn client errors out.
I had found a googled message regarding something similar with the 2.4.22
kernel and tried to the patch-o-matic on it and I suspect that the mandrake
2.4.2-10mdk already has this issue patched since I did not see any patches
that discussed this issue...
I was wondering if there is anything I have missed in the FW rules or if I
am missing load a module...
Cheers and the for any help,
D.
