Network Traffic Being Re-routed
Posted on 2013-05-21
I have a network with 2 HP switches, 2 Netgear switches, a Netgear wireless router and a SonicWall firewall. I have inherited this network, so I am still looking through things, but the only network device that is routing traffic is my Sonicwall Firewall. I also have wireless software called "Untangle" running on a desktop computer. It is routing wireless traffic. My issue is that if I tracert any IP address outside my network, I should see my SonicWall firewall as the first hop, but it's not. The first hop is always the "Untangle" box. I cannot find anything that is redirecting all of my traffic through the "Untangle" box. If I disconnect the network cable from the "Untangle" box, I can't access the internet or any computer outside my network. There are only 2 NICs on the "Untangle" box. One is connected to a wireless access point (separate subnet from my main network) and the other to my network. Is there a good way to track down the device that is forwarding traffic? I have looked through configurations of the switches and routers and have not been able to see anything that is forwarding traffic.
