I have a pair of LHG 60G running 6.45.2 in bridge mode. Everything runs fine for a few days, then eventually I can no longer access the remote antenna via IP address even from the local antenna, but it is still passing bridged traffic from the remote side, and I can still access systems on the remote side. If I log into another device on the remote side, I can then access the remote antenna via IP address, then reboot and everything is fine for a 2-3 days.
I looked at the arp table and didn't see anything strange there.
Thanks
