Hello,
thiago@xxxxxxxxxxxxx a écrit :
nated boxes -> iptables gateway -> internet -> vpn server (runs pptp, and
has iptables also)
Note:1) allways trying one connection at time, 2) connection tracking
module is loaded
I can establish vpn connections (and acctually make use of it) with the
remote vpn server many times, when the requests are originated from the
same box (behind nat); if another computer behind this same nat tries to
connect this vpn server, the tunnel doesn't come up.
Have you tried with the PPTP conntrack and NAT modules ip_conntrack_pptp
and ip_nat_pptp loaded ?
If your kernel is older than 2.6.14, you may need to patch and compile
your kernel with the pptp-conntrack-nat patch from the patch-o-matic-ng
(older than patch-o-matic-ng-20060512).
