I have configured and established a working IPSEC net to net connection using the following instructions
I can ping from any host on either network to host on either network without problems.
My next challenge is configuring a secure firewall that blocks ALL traffic coming in, allows traffic going out using NAT and allows all traffic to come in and out through the IPSEC links on either network without iptables blocking it.
I have been trying to figure this out with no avail.
If someone could give me the specific iptables commands I could type in, I'll just type them in manually or possibly add them to a script. I can find plenty of guides for setting up a good firewall for the average home user but none that assist with net to net connections using ipsec and iptables.
Thanks in advance!
