Hi,
yes - sorry, forgot to mention this. Didn't want to make too much noise...
Next time I'll write if "merged or not". ;-)

Hi,
False alarm. Turns out this isn’t merged, yet.

Okay, thanks for testing this.
I will ask Arne to revert it.

Hi,
perhaps its only me, but after applying this patch for testing purposes I don't see any (redirected) urlfilter block pages anymore.
Only the firewall logs are telling me:
... REJECT_INPUT lo TCP 192.168.100.254 53464 192.168.100.254 81 ...
I had to build a new "Incoming Firewall Access" rule (INPUTFW) allowing TCP traffic from (e.g.) 192.168.100.254/32 to GREEN (192.168.100.254) to TCP port 81 to see a block page again...
Only me?
Best, Matthias

Hello,
This is indeed *very* unlikely, but I am okay with this patch being accepted.

This ensures traffic on the loopback interface matches the IPv4 loopback characteristics (source and destination are within 127.0.0.0/8) and prevents any damage in the unlikely case of non-loopback traffic being injected/emitted (in)to the loopback interface.
