Hello Everyone, I configured SuSE 7.2 to use the recent SuSEfirewall2 with iptables. My system: 2 NICs external eth0 : 10.10.127.99 Subnet: 255.255.255.0 external eth1: 10.10.128.99 Subnet: 255.255.0.0 ADSL-Dialup But no MASQUERADING As instructed I set START_FW2 START_PPPOED to "yes". my "firewall2.rc.config" is also properly configured (I hope) ------- FW_DEV_EXT="ppp0" FW_DEV_INT="eth1" FW_ROUTE="yes" FW_MASQUERADE="yes" FW_MASQ_DEV="$FW_DEV_EXT" FW_MASQ_NETS="10.10.0.0/16,0/0,tcp,80" --------- One thing is very odd: even after deactivating SuSEfirewall2, flushing all IPTABLES and setting them afterwards manually to --------- iptables -P FORWARD ACCEPT iptables -A FORWARD -i ppp0 -m state --state NEW,INVALID -j REJECT iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward --------- no masquerading. I'm desperate! What did I wrong?
