I am totally lost after several tests.
If i replace my PfSense by a PC with the same setup
IP 192.168.10.99
Gateway 192.168.10.254
DNS 8.8.8.8
I have internet doing well
Although the 2 Wans as per first post are OK, the WANGW seems to be not usable.
The ckecks I made:
WANGW is tier2 of a Group Where WAN2ADSL_DHCP is Tier 1 (failover objective).
If I swap Tier1 and Tier2, although WANGW states online, no more access to Internet.
I suspect that the Online state of WANGW is wrong so the group does not swap to tier2.
If I unplug igb0 which is the WAN plug (associated with WANGW) the state remains Online.
I am lost.
Help appreciated, many thanks.
