Thanks for the fast response. I remembered that I have a spare IP on
an ADSL, so changed the setup as follows, based on your mention of a
requirement for a router. This setup still lets me experiment with both
computers in the same room, but is more similar to the final desired
setup:
eth0: 192.168.2.2 ---------- gigE switch ------ eth0: 192.168.1.12
------------------------ ----------------------
| salesns.inxsales.lan | | ns.inxservices.com |
------------------------ ----------------------
eth1: 63.193.79.20 --------- 100 switch ------- eth2: 63.193.79.19
| eth1: 66.134.162.140
ADSL modem |
| SDSL modem/hub
| |
------- internet --------
GRE tunnel (withvan): GRE tunnel (withsales):
63.193.79.20 -> 63.193.79.19 63.193.79.19 -> 63.193.79.20
IP: 192.168.3.1 IP: 192.168.3.2
ip route add 192.168.1.0/24 dev withvan ip route add 192.168.2.0/24
dev withsales
I can ping 63.193.79.19 from 63.193.79.20.
I can ping 63.193.79.20 from 63.193.79.19.
I cannot ping 192.168.1.12 from salesns.
Here are the commands I'm using:
192.168.1.12:
/sbin/ip link set dev eth0 up mtu 1500
