Summary0002165: duplicated or incomplete system access rules
DescriptionIt seems that system access rules have problems when more ips are specified I've discovered this strange behaviour:

This is the rule which allows from two ips:

And these are the created iptables rules:
root@cartman:/var/efw/xtaccess # iptables -nvvL INPUTFW | grep 12345
0 0 ALLOW tcp -- eth3 * tcp dpt:12345
0 0 ALLOW tcp -- eth3 * tcp dpt:12345
0 0 ALLOW tcp -- eth3 * tcp dpt:12345
0 0 ALLOW tcp -- eth3 * tcp dpt:12345
0 0 ALLOW tcp -- eth1 * tcp dpt:12345
0 0 ALLOW tcp -- eth1 * tcp dpt:12345
0 0 ALLOW tcp -- eth1 * tcp dpt:12345
0 0 ALLOW tcp -- eth1 * tcp dpt:12345

This firewall has 2 uplinks this can partly explain the redundant rules?

I have been informed also that with 3 uplinks + 1 on hold a rule which has a source interface: RED allows access from the main uplink only.
(see the attachment for more detail about this problem)

This two strange behaviour can be related. Probably there's something wrong in the cycle statement which iterate and create the rules (this is my guess).

I don't know if this problem is restricted to system access firewall, if not would be a major problem.

happens always when there's both an ip and an interface selected as source.

explision code explodes both, src_ip and src_dev, but there should be a possibility to bind an ip address to an interface, where the explode then will not produce every combination.
