GRE Tunnels are RUINING MY LIFE! Ok, maybe it isn''t that bad. I am a Linux sophmore (for lack of a better term). I have some experience, I have set up a Masq. Firewall at the company''s office as well as one at home. Now... The fun part. LInking the two so I can have access to office network assets from home. Home: External: 65.28.x.y Internal: 192.168.55.1 GRE Tunnel: "ofc" Office: External 216.170.a.b Internal 192.168.5.1 GRE Tunnel: "phome" I have followed the information given in the GRE section, but to no avail. I can''t ping anything through the tunnel created, though it says the link is up. The Tunnel runs from the Office External to Home External (and back)... I used #ip route add 192.168.5.0/24 dev ofc and #ip route add 192.168.55.0/24 dev phome on home and office Firewall/Routers.. I am stuck-ed! On the Home Firewall/Router: #ping -I ofc 192.168.5.1 or #ping 192.168.5.1 Result in %100 packet loss... On the Office Firewall/router: #ping -I phome 192.168.55.1 or #ping 192.168.55.1 Result in %100 loss... Any thoughts? Patrick Dench Application Specialist www.acdisplays.com

This works for me : /sbin/insmod ip_gre /sbin/ip tunnel add alas mode gre remote 213.119.127.168 local 213.119.31.144 ttl 255 /sbin/ip link set alas up /sbin/ip addr add 192.168.1.254 dev alas 192.168.1.254 is also the private ip of my firewall on my LAN /sbin/ip route add 192.168.10.0/24 dev alas This is the remote network Stef -- stef.coene@docum.org "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.openprojects.net
Looks like my GRE problems were due to ipchains. I went to IP Tables, and it looks like it is working. Next issue: name resolution.. Right now the only way I know my home PC is connected is because I turned it on this morning. Is there anyway to resolve PC names through the VPN? Specifically to make it possible to browse another subnet via the Windoze ''network neighborhood''? -Pat Dench
