ATT 3G Microcell

[dwponder]

So I have an ATT 3G microcell that worked on my previous setup. which was modem-router-microcell.  It will not work off of the almond and I have tried putting it in the DMZ and opened the following ports below and assigned a static ip in the advanced network settings.  The only thing I haven't done is at the bottom of the ports listed below is the 4500/UDP After NAT detection, but I already have that port forwarded.  Any ideas on this?  Thanks

TCP/UDP Ports
NOTE:  All ports listed need to be configured for inbound and outbound connections.

    123/UDP: NTP timing (NTP traffic)
    443/TCP: Https over TLS/SSL for provisioning and management traffic
    4500/UDP: IPSec NAT Traversal (for all signaling, data, voice traffic)
    500/UDP: IPSec Phase 1 prior to NAT detection (after NAT detection, 4500/UDP is used)
    4500/UDP: After NAT detection, 4500/UDP is used

As the Microcell [apparently] uses an IPsec tunnel, you should check the following thread: http://forum.securifi.com/index.php/topic,1135.0.html

Thanks for your help.  I wasn't aware that it utilized IPSec.  After disabling it it began to work.  Thanks for the help on that.

And this is why forums are so great 

Thanks for helping out with this.

Technically we ought to create a Wiki section for various modems that don't just work after having been plugged in, but I'm afraid that I don't have time to do this at the moment.

Is this an issue that would affect a samsung network extender for Verizon? If so, I'm not able to open this page on the almonds admin page.... it hangs. Can you help?

Your Almond+ hangs when you try to access the Port Forwarding page?
Which firmware version is yours? If you tap on Software Update in the LCD UI you'll see which version it is.

Been battling with my microcell like crazy. Went to this forum and the turning off the IPsec works instantly. No port forwarding needed

Since the link above for IPsec setting post didn't work anymore I'll post it here too.

1. Open securifi portal on your browser
2. Go to the advanced tab on the top
3. Click on Open WRT
4. Move your mouse over Services on the top and select ALG
5. Uncheck IPSEC box and select save.
6. reboot your router and microcell and you will be up in no time.

Is anyone else still having issues?  I can get my AT&T MicroCell (black model) to work following these instructions but it drops out frequently causing any phone calls I am on to disconnect.  The MicroCell shows the network disappearing and it blinks for a while until it's reestablished.

I've turned off IPSec and also opened up all the appropriate ports.

Any other ideas?

Did you try putting the microcell in the DMZ using the OpenWRT interface?

I have the white version, if there is a difference.  I have only forwarded the ports and been working fine.
