So far - I have a one way vpn and I'm scratching my head.

I guess first I'll describe the hardware setup

Ubuntu LTS Server 10.8.0.1 , running open vpn via TUN
-> Juniper SSG5 with UDP port 1194 forwarded to the Ubuntu server
-> Internet
<- Apple Time Capsule
<- Mac OS X Client Running Viscosity 10.8.0.6 .

The main issue : I can ping the client from the server, but cannot ping the server from the client.

Steps I've taken to debug :
1 - Made sure OS X Firewall was off
2 - Checked iptables on the Ubuntu server, its in accept all mode
3 - checked the routing table on the mac, and all is fine, the route to my 10.8.0.5 gateway shows up fine
4 - My friend Jason is at his own location with the exact same setup [os x, timecapsule etc, his work also has a juniper and ubuntu LTS] - He disconnected from his work and connected to my test environment got the same issues. Then he reconnected back to his work. I think that rules out OS X and Time Capsule. - we DO have different ISP's tho, but i would say that is the only variable.
5 - For fun I tried TCP instead of UDP and got the exact same symptoms..
6 - I did a tcpdump on the client of tun0 and was able to see my ping attempts going thru tun0
7 - when I'm connected, I can't ping 10.8.0.5 [my gateway] - should I be able to?

Does anyone have any idea's ? I feel like I am "this close"....

Thanks.

Disregard. I figured it out.

I was running a client on the server. I mis-read something and thought I needed client.conf on the server for some reason.

All is mostly well now. Rest can be worked out. Thanks.
