Dear all, i am using linux as firewall and proxy server, having some problem regarding Microsoft VPN, my network users connect Microsoft vpn server. the problem is only one user is able to connect vpn, while othere can't do this at same time. if i restart firewall, then any one can connect on First come first server. but only one. so i clear all rules, and default policy to ACCEPT, and used this rule iptables -t nat -A POSTROUTING -i eth1 -s 10.0.0.0/24 -j MASQUERADE iptables -A FORWARD -s 10.0.0.0/24 -j ACCEPT i try this on 2.6(rhel 5) and 2.4 (rhel3)
