Services

I'm seeing problems with the DNS forwarder.  It appears to fail after a while and stop answering requests.  I can get DNS working again by turning it off.  (And refreshing DHCP.)

I see this behavior on two different m0n0 firewalls.  The hardware platforms are a P3-1Ghz, AOpen motherboard and Intel NICs. The other is a Via EPIA 800MHz with an Intel NIC in a PCI slot.  My ISP is Verizon FIOS.
Version: 1.231
Build: generic-pc-cdrom

Any pointers on where I should begin troubleshooting?  This configuration only starting having problems since the 1.2 or 1.3 upgrade.

p.s. FIOS is a PPOE-based service

I can provide a config file upon request.

Just a shot in the dark, but are you low on RAM?

Could also start logging all your udp port 53 lan traffic and check your logs for cues, ie, whether the requests are getting in and coming back out of mono.
