--Sig_/GeI4o0jqrrPvZ29+HtKYRmi Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable 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 amd= 64) I ran out of the sudden into serious trouble. I'm running a VoIP wired telephone on a VLAN, tagged with "2". The router p= rovides 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 ga= teway, 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 AP= U to the recent CURRENT, DHCP stopped serving IPs on all subnets and it wasn't possi= ble 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.=20 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 --=20 O.
