I know my question might sound odd because of the version I'm using but this just because of the type of system I'm running on. Short : I'm running a router with a firewall (Firewall2) using SuSE 7.3 The system is a pentium 200 MHz with 94 Mb memory. I put in attachemend result of different "iptables" commands that show the rules that are set up. Basicaly these are the default rules. My problem is as follow. Before the firewall : Download speed : 320 KB/sec Upload speed : 27,1 KB/sec After the firewall Download speed : 7,2 KB/sec Upload speed : 27,9 KB/sec Ok for the upload, but such a difference for download I don't think this is normal do you? My nsswitch.conf is "hosts files dns" I have eth0 configure to DHCP address from the ADSL ethernet modem I have eth1 configured static 192.168.0.X and eth1:1 configure static 192.168.1.X Can anybody help me for this. In which direction do I have to search for. I'm thinking about first deleting all the rules and keep only NAT. BTW the result of "iptables -t nat|filter -L" can be sended on request. Thank for your help.
