Hello! I have a network with an iptables-based firewall/proxy. Behind the proxy is a machine running Postgres. Recently, many changes were made to the installation. Connecting to the Postgres DB works from within the network, but not from without. I've run out of ideas for tracking down the error... Could anybody kindly pass on some wise advice? firewall iptables (in port number edited): *nat :PREROUTING ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A PREROUTING -p tcp --dport ##INPORT## -j DNAT --to 192.168.2.10:5432 -A PREROUTING -p udp --dport ##INPORT## -j DNAT --to 192.168.2.10:5432 -A POSTROUTING -o ppp0 -j MASQUERADE COMMIT db machine iptables: *filter :INPUT DROP [1:242] :FORWARD DROP [0:0] :OUTPUT ACCEPT [0:0] :LOG_DROP - [0:0] :LOG_ACCEPT - [0:0] :icmp_packets - [0:0] -A INPUT -p tcp -s 192.168.0.0/16 -m tcp --dport 5432 -j ACCEPT -A INPUT -j DROP Thank you!!
