I am attempting to configure a Fortinet FortiWiFi 60C to us a USB 3G modem as a redundant connection, but so far haven't been too successful. I am starting by just configuring it as a standalone interface and will configure the redundancy once that is working.

I am using a Netgear Air Card 320U (formerly Sierra). The modem is recognized by the Fortigate (although as a Sierra AC320U).  I have confirmed that the modem itself works by attaching it to my PC and connecting successfully to the XT network. But when i try on the Fortigate it just sits there saying "Connecting..." but never establishes the connection.

Here is the config I have:

config system modem
    set status enable
    set auto-dial enable
    set phone1 "*99#"
    set extra-init1 "at+cgdcont=1,\"ip\",\"wap.telecom.co.nz\""
end

Anyone out there who has managed to get a 3G modem working on a Fortigate who can help me out?

Thanks

Correction to above, the Fortigate recognizes the modem as a Sierra AC313U

Whilst I have no experience with fortinet I have used the Sierra card and 3G backup on another device (router).

I found that I needed to use the APN 'internet.telecom.co.nz' and it worked where 'wap.telecom.co.nz' did not. It may, or may not work but no harm in trying :)

I would not use the APN wap.telecom.co.nz

Thanks for the suggestions.

Turns out it was because since the router was recognizing it as a slightly different model than what it was it was attempting to access it using the wrong port number. Creating a custom modem definition specifying the correct port has resolved the issue.

Syntax for the APN was correct, and I have found it work with wap.telecom.co.nz and internet.telecom.co.nz. Am currently using internet.telecom.co.nz since that seems to be the consensus of the best one to use.

The issue I am now having is that the IP address that the router is reporting it has been assigned is different to what is being reported to websites (whatismyip.com, speedtest.net etc.) and I can't seem to get it to accept any unsolicited inbound traffic.

What I would like to do is use open port 25 and use DDNS on the modem interface to make it a secondary MX so if the primary connection fails.

I'm quite sure the router config is correct, are inbound pinholes possible on Telecom 3G?

Thanks

Paul

If you want inbound connections you might need to use the "direct.telecom.co.nz" APN http://www.geekzone.co.nz/forums.asp?forumid=39&topicid=32983

Thanks. I've tried that and hasn't made any difference. The device is getting an external and internal address, rather than bridging the external address to the router interface, and I think this is the issue. I've created a new topic under the Telecom XT forum to see if anyone else has got inbound port forwarding to work on XT.

New topic is here.

Thanks again
