I recently upgraded the firmware on my Linksys E3000 to use TomoatoUSB Firmware "E3000 VPN" [tomato-E3000USB-1.28.9054MIPSR2-beta-vpn3.6]. Works like a charm, love all the extra features like WOL. When I go to connect to my corporate VPN however, I cannot connect. "Failed to establish a TCP connection"
I've added port forwarding for the device IP and the ports benign utilized, and even added the device IP to DMZ. No luck. The strange bit is, I reverted back to factory Firmware last night and VPN started working. Fearing a possible setting conflict, I reset to factory settings and upgraded to Tomato again. Without changing a single setting in the fresh upgrade, still failed to connect.
I'm attempting to connect using Cisco VPN Client [5.0.0.07.0440] utilizing IPSec over TCP, port 10,000. Just for due diligence, I've attempted on both wired and wireless connections.
Any assistance would be greatly appreciated
