iptables and MS VPN server
i am using redhat 3 enterprise as firewall and proxy server. due to facing problems i flushed all firewall, nat rules and default policy to ACCEPT. i set this rule to check problem.
iptables -t nat -A POSTROUTING -j MASQUERADE
even setting this i am getting problem regarding VPN (microsoft).
there are 2-5 five users on my network establish vpn to remote network (Microsoft VPN Sever). Any one who try first will connect (Fist In First OUT). when 2nd user try to connect he gets connectivity problem.
This is linux (iptables or etc) problem because i installed windows 2003 NAT server and estableshed multiple vpn same time having no problem.
Any idea to solve this problem
