Thunderbird email application won't download when using wired connection to WRT610N

I've been having problems lately getting my email application, Thunderbird v.13.0.1 to work.  When I directly connect my cable modem to my iMac, it will download and send emails, but not when connecting through the router.  I just updated the firmware to V.2, and still having the problem.  Any ideas?

Try lowering the MTU value to 1400 and try.

Whose your email provider? (yahoo or gmail?) Was there an update with Thunderbird? I found an article about this concern. Hope this helps:

I changed it to 1365, and a couple new emails appeared.  But still unable to send emails - smtp.comcast.net, the status is Connected to smtp.comcast.net, and the Progress bar rolls on, but then I get the Send Message Error - Sending of message files...connection timed out. !?

zee, I did see that article before (I've been working on this problem for over a week now), and tried some of the things suggested, also checked out the Comcast website - and support - that is how I found the problem is when I am connecting through the router.

Try to enable DMZ. Check if that works, we may need to open ports for that application.

Ok, enabled DMZ

with Source IP Address = Any,

and Destination IP = my computer's IP.

 

Still not able to send email, blahh.

I appreciate everyone's suggestions though.

Try to disable the SPI firewall. We have a tendency to disable this feature if we ran out of options. It’s still not recommended to disable SPI firewall on the router because this serves as the protector of your network...

SPI disabled - still not able to complete sending email, it seems to connect to smtp.comcast.net, but the error message says connection timed out.  I used to be able to send almost instantly.

Hi! How about you try triggering this email ports: 25, 110, 113, 143, and 587. For further instructions, you may refer to this link: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=a654a5128d494f9ebb04c742b9230d3a_4596.xml&pid=80&r....
