Ericsson F5521GW, 3G, PPP setup and configuration.

[pmellen]

Hi All,

I have a pfSense appliance SG-2440 with the 2.3.3-RELEASE (amd64).  I have installed an Ericsson F5521GW 3G modem.

• The modem connects to the mobile network, checked with "Status -> Interfaces", shows status as "up" with an IP address.

• Using the "Diagnostics -> Ping" feature, I can ping google.com.

However, there is NO connectivity from the LAN network to the public Internet (using the F5521GW).

I'm sure I'm missing something obvious, but I don't know what that is? All help and assistance greatly appreciated.

These are the steps I followed. Tell me if further logs or configuration details are required?

First, checked compatibility and on;

Then followed configuration guide;

N.B. To enable PPP interface, assign as WAN, as per YouTube videos

Added init string as per;

N.B. It may (or may not) be obvious, however, Use " at start and end of init string.
