Antec M1424WR (Rev F) DMZ not working? Microcell related

Ok, can anyone here tell me why a device that is sitting in the DMZ (in this case my 3G Microcell) with the Lowest firewall settings enabled would generate this type of blocked traffic?!?!? 

Jul 26 11:03:43 2011Outbound TrafficBlocked - Default policyFirst packet in connection is not a SYN packet: TCP 192.168.1.2:43749->12.230.208.44:443 on clink1

This is just generated over a 15 second period.  I am seeing TONS of this blocked traffic with 192.168.1.2 in the DMZ.  NO WONDER MY MICROCELL will not sync with ATT

**** CONFIRMED SOLUTION *****

The Actiontec router is the problem.

Today I called verizon and had my ONT switched to ethernet.  Then replaced that router with an old Linksys router that I loaded DD-WRT on.  I reset everything to default on the DD-WRT router, then I connected my DIR-825 (DHCP turned off) router to that.  Did a few tests to check my ping and speed.  All was good.

So then I plugged the cat5 cable from my ATT 3G Microcell into the DIR-825 router.  And in the time it took me to login to the DDWRT router and to make sure that it gave the Microcell an IP, I received a text from ATT saying my microcell was successfully activated. 

These actiontec routers are complete junk... case closed!

here is the response I got from Antec:

Resolution:
=========================
Some ports may be being blocked by Verizon unintentionally.
It used to be that residential DHCP services had several ports blocked.
20-21 ftp server ports
25 and 110 POP and SMTP server ports
80 and 443 Web and Secure Web server ports
The DMZ Host should have unblocked every port including 443 and no, there are no known issues with DMZ Hosting at this time.

Is 192.168.1.2 the IP address your Microcell has been locked to use? I presume so, but have you tried disabling the firewall entirely on the ActionTec to see if it will sync up with AT&T and if those entries do in fact stop? The DMZ should be as you described; meant to bypass the firewall. On some routers, I have seen some exceptions to that rule however and those usually involve cases that would trigger any firewall on the spot.

Yes, its was assigned that through DHCP and then I gave it a static lease. 

There is no option to turn off the firewall completely on these models.... I WISH!

I've gone through every setting in this router to try and find why it would block 443 inbound and outbound... but there is no setting  that I can find.

If there is "No Security" option under the Firewall, try the Custom option and do not create any rules for it. I imagine it should work almost as if the Firewall were switched off.

There is no such thing as a custom option.

Verizon replaced my router with another (Rev F) and its doing the exact same thing......  JUNK

I did however go into advanced routing and try to create my own dmz by entering this for incoming:

Any 192.168.1.2 microcell - TCP Any -> Any
        UDP Any -> Any Accept Connection Active

and this for outgoing:

192.168.1.2 Any microcell - TCP Any -> Any
        UDP Any -> Any Accept Connection Active

and the logs STILL show inbound and outbound connections to ATT being blocked by the router... seriously these routers are GARBAGE!

The routers themselves are not garbage. The firmware is actually the problem with them. DD-WRT on the ActionTecs works like a charm though the problem with that is you lose MoCa (Coax) support on the ActionTec.

I wish I could put DD WRT on this router... but I am hooked through coax 😞

If you don't have TV service and you have some time to get the ONT switched over to Ethernet (you'll need to run the cabling yourself to avoid a tech roll and fee), DD-WRT is still a possibility. You just need to be sure your version of the ActionTec router is compatible.
