Captive portal sending RST
-
I've got a pair of pfsense boxes in failover which have been working fine. They're on 2.6.0 so I thought it might be an idea to test an upgrade to 2.7 before doing it in production.
So I've set up a couple of VMs and restored the config from the production boxes on them. It's a segregated network so the LAN side is identical to production.
Unfortunately the captive portal isn't working. I can see it's redirecting, as the url in the browser changes to the hostname of the captive portal with the ?zone=etc stuff, but the page never loads.
Looking in packet capture it's complaining about duplicate TCP transmissions and sending RST packets.
Any ideas what might be going wrong?
