Perhaps someone can help me here. I am trying (exhaustively) to get my
PPTP server behind a firewall. I believe that I almost have it working,
but one minor thing stands in my way.
I receive this message on the firewall when attempting a PPTP connection:
Apr 16 13:22:47 odo kernel: ip_masq_gre(): creating GRE masq for
172.28.254.46 -> 12.19.228.58 CID=0 MCID=643A
Apr 16 13:22:47 odo kernel: ip_demasq_gre(): 12.19.228.58 ->
12.19.228.52 CID=0 no masq table, discarding
For some reason, the MASQID is getting lost between the masqing &
demasq'ing of the GRE packets.
I am running IPFwd --masq $IP 47
I have John Hardin's PPTP kernel patch running
(both on the firewall).
And I know that the PPTP server works becuase i can successfully connect
when I remove it from behind the firewall.
Can anybody help me here???
Thanks
