roninhockley Posted February 10, 2006 CID Share Posted February 10, 2006 I am using a Shorewall linux box to manage my 6 incoming static ip's and to provide NAT translation for my workstations out to the net. With the NAT on, I am losing about 100K of upload speed. I usually get 440-450 Kbps but i am getting 340 Kbps thru NAT. Does this sound normal? I can understand some latency in translating addresses going out, but this seems excessive to me. FYI: I have Oplink DSL, the plan is 3Mbps down and 512Kbps up. I get really good speeds because my office is 800 ft. from the junction box. Quote Link to comment Share on other sites More sharing options...

Swimmer Posted February 12, 2006 CID Share Posted February 12, 2006 I looked around.. it seems that is just what happens with shorewall.. I found your other post on expert-exchange.. I dont know enough.. but you might want to try http://www.fs-security.com/ <-firestarter http://www.simonzone.com/software/guarddog/#screenshots <-Guard dog http://m0n0.ch/wall/ <-monowall http://www.smoothwall.org/ <- smoothwall There is no guarentee that those are going to solve the problems.. but they might be worth a try if 100k is that important. BTW welcome to the forum! Quote Link to comment Share on other sites More sharing options...
