Hi all, I'm trying to customize my iptables rules. Let us imagine we have three hosts which users have to access: HOST1 HOST2 HOST3 Is this configuration correct? Iptables -N HOST1_RULESETS Iptables -N HOST2_RULESETS Iptables -N HOST3_RULESETS In each new chain, I will add rules to accept connections to some services like telnet, ssh, IBM Client Access. And after, I will do this thing: Iptables -A FORWARD -i eth0 -o eth1 -j HOST1_RULESETS Iptables -A FORWARD -i eth0 -o eth1 -j HOST2_RULESETS Iptables -A FORWARD -i eth0 -o eth1 -j HOST3_RULESETS In fact, what I'm looking for is that I can organized my rules by hosts instead of adding all rules to all hosts in FORWARD chain ? With the configuration, I describe, will all rules in the HOSTX_RULESETS being check ? I think, it's correct but I'm not totally sure.
