How do you change NAT Type on the Vita?

[a3069namebke]

I checked as I always have problems connecting to others on the vita, and I have a NAT Type 3. What's strange is I have a NAT Type 2 on PS3. How do I change it, so I could get some online trophies?

You'll probably have to make some adjustments at the router, e.g., port forwarding or create a DMZ or lower the router's firewall security settings for the Vita.

what model of router do you have?

You might just need to open a few doors to Vita, but beware of some compatibility issues on port forwarding

I had a similar issue...I tried pretty much everything (port forwarding, dmz etc) but in the end I changed my router and that fixed the problem. The original router was a Thomson Gateway BTW.
