I use PFSense 1.0.1 embedded on a WRAP board.
There are two WANS, both get a network-address through DHCP.
Lets call them 1 and 2. 1 being the ISP on the WAN, 2 being the ISP on OPT.
Most things work fine, but the DNS forwarder has problems. I found it this has to do with the static routes.
I've put static routes to the ISP's DNS servers:
Interface Network Gateway Description
OPT DNS-server2 Gateway2 DNS forwarding to DNS-server2
WAN DNS-server1 Gateway1 DNS forwarding to DNS-server1
For some strange reason, the route to DNS-server2 gets deleted after a while.
route monitor showed:
got message of size 132 on Wed Mar 14 13:10:56 2007
RTM_DELETE: Delete Route: len 132, pid: 21396, seq 1, errno 0, flags:<GATEWAY,DONE,STATIC>
Anyone any idea why they are deleted?
