14.13. Configuring the Firewall of the Arctic
Typically at least the “GPRS to Arctic” firewall should be enabled. For normal use, the following
protocols/ports would be allowed: ICMP (ping), 80 (GUI), 22 (SSH), 23 (Telnet), 2402, 2404 (Serial
GW).
The “GPRS to LAN” should be denied in normal cases and “LAN to GPRS” typically allowed. The
setup varies case by case. VPN tunnels are excluded from firewall configuration (set as allowed).
Note: The “ANY” protocol option should be used with caution. In addition, if the protocol/port fits to
“Accept” rule, any “Drop” rule for the same protocol/port in the list below
the “Accept” rule has no
effect.
Note: Verify that you have enabled the firewall in the “Enabled” part of the menu and also enabled
each firewall that is needed individually at firewall’s settings page in “Use <firewall>” “Yes/No”
selection.
