IP MASQ and VPN client.

["Anthony Coley" <dillweed13 hotmail com>]

Hi,

I have IP MASQ working with my internal network and it works great.  But, 
I'm having some problems properly configuring my IPCHAINS to allow my 
xtranet VPN client to connect to my office.  This is how my IPCHAINS are 
setup:

--start--
#
# Turn on IP forwarding
#
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -s 192.168.1.0/255.255.255.0 -j MASQ
# /sbin/ipchains -A forward -s 192.168.1.1/255.255.255.255 -j MASQ
# /sbin/ipchains -A forward -s 192.168.1.2/255.255.255.255 -j MASQ
# /sbin/ipchains -A forward -s 192.168.1.3/255.255.255.255 -j MASQ
/sbin/ipchains -A forward -s 192.168.1.3/255.255.255.255 -d xtranet.bmc.com 
-j ACCEPT
--end--

I'm using RedHat 6.2 with the 2.2.14-5.0 kernel.  Can someone help with the 
proper syntax to configure my VPN clinet?

Thanks,

Anthony
