hello
i have just installed cfs everything is working fine even our squid proxy server
but our vpn service do not work when cfs is enabled
we are using ibsng for giving vpn accounts
these are the rules we use for iptables for pptp service

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A INPUT -i eth0 -p tcp --dport 1723 -j ACCEPT
iptables -A INPUT -i eth0 -p gre -j ACCEPT

i tried adding them to file csfpost.sh and restart cfs . at the ending line after cfs restart it says its using csfpost.sh too
but again nothing client can not connect to server at all using vpn till i disable cfs
thanks for help
regards

edit 1 :
well at least i could solve one problem
i added csfpre.sh and added my rules

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A INPUT -i eth0 -p tcp --dport 1723 -j ACCEPT
iptables -A INPUT -i eth0 -p gre -j ACCEPT

to it and now clients can connect to server
but still they can not browse or open any page
what should i configure to solve this ?
