Nat stopping OSPF working

Hello

my whole network uses OSPF, runs really well all OK except one router in our office.
It won’t fill the routing table on reboot.

I found out if I disable NAT on the router it will then work fine.
I can enable NAT after a min and it will stay working fine till next reboot.

Any Idea’s on this?

Thanks

Rhys

Can you upload the config from the affected system? Also try enabling OSPF debug and see what the log shows during the problem phase.
