Hi all,
KUDOS to all IP Gurus who helped me reinstall our ATHnet AMPRnet GATEWAY in Athens, Greece. Special thanks to Marc, Tom, Brian N1URO and Brian Kantor whose comments and WEB PAGES helped.
An easy iptables script would also be a good help to us but I think that I am OK at the moment using UFW and also Brian N1URO's ideas on how to allow IPIP in my LINUX box using 3 IPTABLES commands I found in his WEB PAGES/POSTINGS.
Thanks a lot guys. Your help is much appreciated!
