In IPFire's WebUI, the routing page ("static routes") crashes with the following log message in /var/log/httpd/error_log: [Wed Aug 30 20:34:24 2017] [error] [client 10.XXX.XXX.XXX] Undefined subroutine &General::check_net_internal called at /srv/web/ipfire/cgi-bin/routing.cgi line 157., referer: https://10.XXX.XXX.XXX:444/cgi-bin/routing.cgi This can be reproduced by adding a static route with the following data: IP/Network: some internal IP (such as 10.99.101.1)/255.255.255.255 Gateway: GREEN IP of the firewall Comment: leave blank Since other routes are processed correctly, I assume this is a bug. At least an error message would be nice, but the WebUI just returns a blank page in that case.
