How I can combine a few addresses in one rule? For example, I'd like to add two IPs 10.10.10.1 and 10.10.10.2 to the same rule.
Either use ipset (needs a patched kernel), or iprange (if the addresses are consecutive) or use a subchain, e.g:
-A -s 10.10.10.1 -j CUSTOM -A -s 10.10.10.2 -j CUSTOM -N CUSTOM -A CUSTOM <rest of rule> HTH, M4
