I just installed a 305 with 2 cable modems attached. I have a Mikrotik router behind the 305. Everything is working fine (or seems to be, but I cannot monitor the Mikrotik from outside the network). I need to create the rules, access, etc to allow me to use the Mikrotik Winbox interface to access the Mikrotik router. The Winbox GUI uses port 8291. I have been unable to get the 305 configured properly for this. Any suggestions or config advice would be greatly appreciated.
