Hello !

 I am trying to build CIPE VPN network on
my Firewall with Redhat9 now.

 It seems that GUI tools made an original config
file into /etc/sysconfig/network-scripts/ifcfg-cipcb0.

 In Redhat9 security-manual and Web information,
the config file is /etc/cipe/options.cipcb0.

 It make me too confuse.

<Case1>
 LAN1==Firewall-A==Internet==Firewall-B=LAN2
<Case2>
 LAN1==Firewall-C==Internet==Dial-up Client

 I guess, the config on Firewall-C can use for B and C.
Because, Even if Firewall-B is using Dynamic DNS,
Firewall-A can receive UDP packet such like C.

 Using NAT, (in Redhat security-manual),
(iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE)
Can this filter prevent to forward NetBIOS to internet by the other iptables
?
If there is....
iptables -A FORWARD -o eth0 -p tcp --sport 137:139 -j DROP
Can CIPE work correctly ?

Please advise !
