The firewall rules are processed from top to bottom. If strict rules are wanted,
last rule should be DROP.
The parameter “From IP” can be used for limiting access based on IP address.
For example “192.168.100.0/24” would limit access only packets coming from
192.168.100.0 network.
Figure 26. GPRS Settings
These rules would allow incoming connection to GPRS interface: ICMP, web
(TCP port 80) and telnet (TCP port 22) from any IP access.
