It's possible. I have configured several vpn links using GRE on
linux.
You'll need to load the GRE module and put a simple rc file to
initialize the tunnels
The rc. file looks like this
/sbin/insmod ip_gre
/sbin/ip tunnel add tunnel0 mode gre local 200.xxx.xxx.xx remote
200.yyyy.yyyy.yyyy
/sbin/ifconfig tunnel0 172.20.3.178 dstaddr 172.20.3.177
/sbin/route add -net 192.168.0.0 netmask 255.255.255.0 dev tunnel0
