I’ve set up some basic firewall rules to allow traffic in for example port 25 on chain Forward. 1 ETH01 * ACCEPT tcp opt — in ETH01 out * 0.0.0.0/0 -> 0.0.0.0/0 tcp spt:25 dpt:25 no This works fine when I have the chain’s policy on ACCEPT – but as soon as I switch it to DENY, this port appears to be blocked – even though I’ve explicitly allowed it through. I’ve also tried keeping the policy setting on ACCEPT then adding a rule lower in the sequence to DROP all, thinking this rule will be processed last but to no avail! 18 ETH01 * DROP all opt — in ETH01 out * 0.0.0.0/0 -> 0.0.0.0/0 I’m running Release 2.0.RC2. Please help! Thanks, Ian February 9, 2013 at 9:32 pm #52655 JamesRMember How about posting a dump of the firewall table?
