Topic: problem with PPTP

VPN connection works in England and in France.
If you have a firewall, it must allow DNS, HTTP, HTTPS requests and allow access to UDP 500 (isakmp), protocol IP 50 (ESP) et UDP 4500 (for NAT traversal) ports.


how to allow all this in my IPTABLES?


thanks is advance!

Re: problem with PPTP

this is iptables to allow outside to go inside

$EXTIF is interfaces to go outside

$IPTABLES -A INPUT -i $EXTIF -p tcp -m tcp --dport 80 --syn -j ACCEPT

you choose change port to udp 53 for dns , 80 for http, 443 for https

you may show your firewall then i can tell you more.
