Hello again and thanks a lot for answering me, > For issue 1, perhaps you are blocking ICMP traffic on eth1? No, I do not block anything as far as I know regarding ICMP. This configuration I use for iptables: echo 1 >/proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE iptables -t filter -A INPUT -s 192.168.0.0/24 -j ACCEPT iptables -t filter -A INPUT -s 192.168.1.0/24 -j ACCEPT iptables -t filter -A INPUT -p tcp --dport \! 8901 -j DROP btw. do you know why I cannot connect to the internet from localhost if I set the last line? I tried to set -s !127.0.0.1 but this also seems to not work :-( > For issue 2, ip_forward needs to be set to a 1 (not part of > iptables). > > Take Care! Is this really anything I need to do since I already set it to 1 Hope I am not nerving, thank you in advance, lg Clemens
