I have a problem with Captive Portal and I think it may be a bug.
I have a Monowall with Captive Portal enabled on the LAN segment. On that
segment, I have a router connecting to another segment with a different
subnet (DHCP for this subnet is served by the router). I've added static
routes as needed and can get DNS resolution by a client on the other side of
the router, but when attempting to browse the web, I get redirected to the
captive portal login page as expected, with one major difference... The
captive portal page is completely blank for clients on this new subnet! (It
just contains some standard HTML tags, and not the captive portal page seen
by other users on the LAN segment...)
Any ideas where I need to start looking in the code?
