Working great except when using DHCP for WAN interfaces
To solve a double NAT situation, I configured my modems for bridged mode and set the pfsense firewall WAN interfaces to pull public IP addresses via DHCP. Everything is fine until a modem hiccups, or possibly gets a new IP (not sure which). Suddenly, computers on the LAN have problems getting out or other bizarre behavior.
A gateway will always show down while this is going on and never seems to recover without a reboot. I just reboot the firewall and everything is fine. I don't remember this ever happening when I had the WAN interfaces set to private IP's, and let the modems handle public IP renewal (firewall IP's were in the DMZ's of the modem networks).
In Advanced/Misc/Gateway Monitoring, the following is checked: "State Killing on Gateway Failure"
Could this be the problem?
Any idea what's going on? This probably makes no difference, but I have no problems coming in, e.g., VPN to the computers with the problems while this is happening. I could just go back to double NAT, but I'm curious now and would prefer to only change what's necessary.
EDIT: more info. The gateways are set to "Dynamic" and monitoring is enabled (Disable GW monitoring is unchecked). I have load balancing and failover GW groups.
Found a similar issue here:
The problem I'm seeing is exactly the same as this post - " reetp commented on Aug 10 "
I also found more wan failover / recovery issues on the day I posted this. I didn't save the links though. No solutions there anyway. Maybe old/known problem.
Also described here. Odd that DHCP on the WAN causes problems, but static wan ip doesn't.
