Getting openvpn working

["dj_segfault" <user=60@nabble.blu.org>]

 So I'm going away this weekend (unfortunately that means I won't be at 
the installfest).  When I travel, I'm kinda stuck with webmail, because 
I was never able to get authenticated smtp working.  So I figured I 
would try vpn. 

I'm following directions from here: 
http://blog.fourthirty.org/?p=135. 

Stats: 
server = Fedora 8 
client = Ubuntu 8.04.1 

I actually have them connecting, so all the keys are working.  But when 
I try pinging the server as the directions indicate, it just hangs. 
Note that I'm doing this test while I'm at home connected to my network, 
but I don't think that will make a difference.  I'm going to try it from 
work tomorrow.  Also note that I normally connect to my server through 
my intranet as 192.168.1.3, and for some reason the directions had me 
set up the vpn to 172.16.0.x.  I would like to get this working such 
that when I'm outside my network, I can access my server as 192.168.1.3, 
just like when I'm on the inside.

When I ping, I see this in my server logs repeatedly: 
Aug 19 23:51:58 janus kernel: Unknown OutputIN= OUT=tun0 SRC=172.16.0.1 
DST=172.16.0.6 LEN=84 TOS=0x00 PREC=0x00 TTL=64 ID=28010 PROTO=ICMP 
TYPE=0 CODE=0 ID=52260 SEQ=1 

No errors on the client side. 

Any clues? 
Thanks.  Oh, I'll also have it at the meeting, if we have network.
