ISPConfig Firewall is blocking my public network
I have the folowing situation:
---INTERNET-------ISPConfig Server/Router ------ Switch ------ other computers
Before installation of ISPConfig the router/server was route-ing a public subnet 86.122.*.*/26 using (in Debian) /etc/sysctl.conf net.ipv4.conf.default.forwarding=1
and all of the other computers in my network where using public ip-s. In fact through eth1 i was using public IP-s from the same subnet inclusive for DNS...etc.
Everything works fine until I enable ISPConfig firewall, but after that, the other computers in my network (not the server) doesn't have internet anymore. I could ping the router/server enabled ip-s, but i couldn't ping yahoo, google etc
Thank you very much in advance.
