[techtalk] linux vpn/routing

[JLG]

I have two clusters of web servers that I need to set up a
VPN between. Each server has 2 nics: eth0 has a public address
				     eth1 has a private address,192.168.x.x

Here's a (crummy) illustration


192.168.1.170 eth1 -WWWSERVER1- eth0 AAA.BBB.CCC.170 (public)                          
      |					|
      |					|
    VPN BOX1--------------------------GATEWAY1 AAA.BBB.CCC.1
					|
					|
				    Internet
					|
					|
    VPNBOX2---------------------------GATEWAY2 DDD.EEE.FFF.1
      |					|
      |					|
   192.168.2.4 eth1 -DBSERVER- eth0  DDD.EEE.FFF.4
      

           
Before I can start adding encryption into the mix I need to resolve
some routing issues. Will it be possible for me to get 192.168.1.170
to ping 192.168.2.4 ?
what routes are neccessary?

please let me know what other information I can provide to be more
helpful. I guess first i need to know if this is possible. It seems to me
that you can probably do it as long as both public interfaces can reach
eachother. I just feel like I am not looking at this correctly.

thanks in advance,


Jen
