Broken firewall after move to new premises.

[The_Sage]

Hi, Has anyone had the experience of setting up a OPNsense firewall  to work how you want and move it to another location to have it FAIL.. (in particular Squid with SNI, a few SSL Bump additions, a restrictive firewall to allow only web access through the proxy)
 
 This  setup works like charm, with speedtests  (speedtest,net) reaching maximums I have recorded.
I then take this fire to a customers premises and change the WAN IP address, reset up the gateways, etc. to have the firewall just be a brick.

The only change is the WAN IP address and Gateway. web browsing is sporadic and random. there appears to no issues looking at the logs in the GUI.

I haven't been able to look any more closely, as I needed to get this firewall going for the client (had to set to up like an ISP modem  ). I then take the firewall back to the office, change the Gateways again and it works as expected.

Another random issue, with 18.7 was trying to get the Failover going. After 2 weeks (client break ) I went to troubleshoot, and the fail over was just miraculously working. NO CHANGES.

Is there any sort of caching, in RRD databases, Squid Cache etc that may Cache or otherwise still retain the OLD WAN address and or gateway ? (This is the thread I was troubleshooting the with this older gateway issue).

Has anyone had any similar issues?
