My computer is connected to the Internet via a Verizon Ellipsis Jetpack. When I use the Jetpack, I can use a mIRC client to connect to the EFNet, but with the same client I cannot connect to the Undernet. On both connections, I use port number 6669. If I use a different wireless connnection with the same computer, I can connect to both networks. Any help/suggestions would be appreciated.
