NAT problem(?)

I have two routers...

First provides the networks wireless capabilities, has UPnP and NAT options.

Second is the outter router providing the first with internet (2nd DMZ's the first), this also has the two options.

On MSN it can loose connection sometime and my connection overall is quite unstable, doesn't perform to well on Ares etc. (No firewalls installed etc.).

"You have a UPnP symmetric NAT" - basically an error with the triangle yellow !.


Any ideas on what configurations to use in regard to UPnP/NAT settings?

Also on my ISP settings (on their website) it says NAT is enabled, could this be the problem? Do other ISPs always use NAT? (I was with Fast4 before).
 
as far as l know NAT is at router level, so many words a firewall..

my personal opinion is l dont touch UPNP, hence its always turned off, however if l need ports open l will open them manually via port forwarding, that really what this boils down to imho

ISP saying you have "NAT" more than likely means you have a single static / dhcp assigned IP and need to run NAT internally for more than a single device.

My immediate answer would be why don't you get a block of 8 IPs, use one for perimiter router and dmz devices and another for the "internal" router.
I would suspect that would be problem solved.

Well could I have the NAT turned off at ISP level and just have it at my router level?

Also about the block of 8 IPs, I'm a bit confused, already one IP is assigned to the outter router, the outter one then assigns an internal IP to the inner router then each computer has its own IP set on its adaptor in the settings.
 
I decided to get rid of the other router and just have one Linksys running.

Although I have set the ports, they still seem to be closed when running port checks.

Any ideas?

(Linksys WAG354G).

MSN currently says... "connected through a non-UPnP port restricted NAT".

NAT is on, on the router.
UPnP is off, on the router.

thats not exactly what he meant.. the IPs assigned to your computers are "local" so they can only be called upon locally, however the way the rep was trying to explain would generally be more trouble than its worth, but technically if you so wished you could have an external IP for each system.. you could venture to say tho that it would be doing something similar to a webserver...

Checked that guide out before and did the utorrent port checker and http://www.canyouseeme.org/ and both showed that ports were still closed.
