[-- Attachment #1 --] Utilising a PCengine APU 2C4 as a router/gateway/firewall with IPFW running recent CURRENT (FreeBSD 12.0-CURRENT #24 r311637: Sat Jan 7 11:03:15 CET 2017 amd64) I ran out of the sudden into serious trouble. I'm running a VoIP wired telephone on a VLAN, tagged with "2". The router provides on the same NIC (igb1) a usual LAN with some hosts on a network, say designated 10.0.0.0/24. On the same interface, the VLAN 2 is designated with 10.0.200.0/24. On this gateway, there is IPFW as default firewalling instance and net/isc-dhcp DHCP Server 4.3.5 as DHCP server. Since around the end of the week two weeks before after an update of the APU to the recent CURRENT, DHCP stopped serving IPs on all subnets and it wasn't possible to ping the LAN 10.0.200.0/24 any more (routing is done via static routes) from 10.0.0.0/24. I can ping all subnets from the gateway/router APU itself without problems. The fun part is that I didn't change much in the meanwhile, but I did some reconfigurations on IPFW, but even when completely openingen the IPFW by a allow all rule doesn't solve the problem. It is driving me crazy, since even with the configs it worked before, I don't stand a chance with the recent CURRENT as shown above to restore functionality. I guess I have a major problem in my configurations and need some advice. Thanks in advance, oh -- O.
