My office just got a Utopia connection. We're using a great linux distro called ipcop to handle our firewall/vpn needs. For some weird reason the hardware that utopia installed does not like our firewall. When we hook laptops directly up to the connection we get 15 Mbps, but when we hook up the firewall we get about 1Mbps. We tried two different NIC chipsets (Realtek and SiS) and they both gave us the same problem. The Utopia technicians are dumb as a post and haven't been able to help us at all. Can any of you recommend some troubleshooting ideas that could help me to diagnose the problem? Since I'm troubleshooting this remotely I basically only have ssh access to the firewall so any diagnostics I can run from the command line would be best. Our ping times with Xmission (our Utopia provider) are normal (2-3 ms), but our throughput is abysmal. mii-diag tells me that both of our active NICs (the one connected to Utopia and the one connected to our LAN) are running at 100baseTx full duplex. /sbin/ifconfig says there are no errors or dropped packets on either eth0 or eth1. Any other ideas? I don't have much experience at diagnosing bandwidth problems like this.
