DHCP client on WAN interface broken in 2.0-RC1 ?

[quisam2342]

I'm using pfSense on a leased root server from Strato.
They have a somewhat special network config.
The server has a /32 netmask and needs an additional
interface route to the default gateway.

With 1.2.3 DHCP on the WAN interface works out of the box .
With 2.0-RC1 the default route is missing.

On the shell I can add the routes by hand:
route add -host 85.214.128.1 -link em0: -interface
route add default 85.214.128.1

Where should I add the routes?
In the GUI? In some files?

Any comments are welcome!

Which build of RC1? RC! install or upgrade from 1.2.3?

You could start in System -> Routing, click on the Gateways tab and the clik on "+" to add a gateway.

Since 1.2.3 worked without special tweaks for the default route I'd guess 2.0 should also. Depending on what build of 2.0 RC1 you used you may get better results with a recent snapshot build of 2.0 RC1.

I have done a fresh install of pfSense-2.0-RC1-amd64-20110226-1807.iso

Now I made an upgrade to the Latest Version: Sat Mar 26 00:18:39 EDT 2011. The problem still exists.

With this little hack it works for me:

/etc/dhclient-exit-hooks:
#!/bin/bash
if netstat -nr | grep -q '^default'; then
 # default route exists
else
 route add -host $new_routers -link em0: -interface      
 route add default $new_routers
