Severity: important

After apply the latest patches my openvpn tunnel broke down.
Downgrading to cipher 0.9.8g-15+lenny6 (my previous version) brought the tunnel 
up again.
Openvpn did start ok, interface went up, logs stated "connected to peer" but 
the tunnel was non-functional.

I have production state on this tunnel so I had lack of time in investigating 
underlying causes.
If you provide me with your wishes I can do tests under controlled 
circumstances.
Do the logs indicate any kind of error message?

Can you try exactly which version broke things?  Can you for
instance try if 0.9.8g-15+lenny8 still works?

I've tried this with 0.9.8o-3 which has the same patch as
0.9.8g-15+lenny9, and it still works for me.

I can also try this with a lenny based system, but I'm not going
to try this this late in the evening.

Hi Kurt,

I just tested with libssl0.9.8_0.9.8g-15+lenny8_i386.deb and it works fine.

just to be clear: I buy this tunnel as a service from an ISP to obtain a public, fixed ip address. I have no control about the config and I have ignored the WARNING in the bottom of the success log because the openvpn.conf was created by the ISP.

I interpret the Warning as interface is brought up correctly and the server (my peer) is sending a somewhat misconfigured route.
An error but it indicates a fully established tunnel.
