When connecting with the Cisco VPN Client though Verizon Evolution-Data Optimized (EVDO) wireless connection, TCP connections do not get established

Core issue

EVDO is a CDMA-based wireless broadband Internet service that offers throughput of up to a theoretical maximum of 2.4Mbps.

This problem  occurs when  compression is enabled and all the TCp traffic is sent to a verizon proxy.

A  behaviour to be noted  is when trying to access a server on a TCP port behind the tunnel, the server does not respond. However, other applications like ICMP are fine.

Resolution

To resolve this issue, perform these steps:

  1. Launch the VZAccess Manager.

  2. Under the connection properties for the specific connection entry, there is a tab called "Venturi". On this tab, disable the Compress and accelerate WWAN connections option.
