Let's compile a list of providers and how they affect NAT. It's not always a router issue.
1) Globe - restricts port opening.
2) Globe Business - does not restrict port opening (oddly the lowest plan costs the same as the 1299 residential plan, BUT you cannot switch from residential to business if you haven't finished your contract.)
3) Smart Bro - Heard that this does not restrict port opening, but be wary of the fair usage limits :3
4) Sky Broadband - My Current provider (got the bundle that includes the silver cable package
) no NAT.
Please post your experience with the other providers.
DE people, are you planning to partner with a specific ISP for ads and stuff?
