NAT randomly stops working
Xefan last edited by
I got some sort of strange things happening with pgSense.
There's a LAN network connected to internet through NAT on pfsense. Sometimes some host could stop accessing (http or icmp) web-site, as others can access it at the same time. It happens to different hosts.
When I look at Queries I don't see any drops. Same with the interfaces - all is ok.
Please help me with this issue!

Nothing special at the logs, mostly ntop messages.
I tried tcpdump and figured out that all packets are going correctly. Seems like NAT doesn not send/recieve all packets to clients…
