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=20 have some experience, I have set up a Masq. Firewall at the company's = office as=20 well as one at home.

Now... The fun part. LInking the two so I = can have=20 access to office network assets from home.

Home:

External: = 65.28.x.y

Internal:=20 192.168.55.1

GRE Tunnel: = "ofc"

Office:
External=20 216.170.a.b

Internal=20 192.168.5.1

GRE Tunnel: = "phome"

I have followed the information given in the GRE = section,=20 but to no avail. I can't ping anything through the tunnel created, = though=20 it says the link is up. The Tunnel runs from the Office External = to Home=20 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=20 stuck-ed!

On the Home Firewall/Router:

#ping -I ofc 192.168.5.1

#ping 192.168.5.1

Result in %100 packet loss...

On the Office Firewall/router:

#ping -I phome 192.168.55.1

#ping 192.168.55.1

Result in %100 loss...

Any thoughts?
