Our company just installed a Netgear UTM9S and I've been trying to get our server visible to the outside world.
I've gone into firewall settings and set up a new rule that states all incoming HTTP traffic be forwarded onto 192.168.1.82, port 8881.
For a while the server is visible when visiting the building IP address from both on and off the network, but for some reason our internet will cut off after about 10 minutes and the firewall admin panel is not available. The only thing that can be done is to power cycle the firewall and delete the rule.
I'm pretty new to networking in general, so any advice would be greatly appreciated.
