HELP: router-router LAN-LAN

[ESToomere]

My problem:
I used to be able to host games on my old router, got fibre internet which meant upgrading to a new router. The new router has fucky ports/UPnP which reserves all UDP ports, Telnetting and blasting the suckers didn't work.

My idea:
What if I bridge the old router to the new router? I think I can only do LAN-LAN though, so essentially, a dedicated gaming router (but with the same SSID and WAP so there won't really be a difference AFAIU).

My question:
Will this work? The old router is already port forwarded, will the Strict NAT still apply since it goes through the first router? Is this just my lunatic typing at 1 AM or an actual solution?

Yes that could work. You might need two external IP addresses though depending on how good the fibre router is.

 

We use a similar method at work for our branches.

We turn off NAT etc on the billion and just have it hold the connection. the heavy lifting is all the cisco.

 

Edit- Basically it might work on your set but can't say for sure without seeing your set up.

My main issue is that Router 2 has no WAN port, so I HAVE to make it a LAN-LAN slave via Router 1. This seems kinda cavemany if Router 1 blocks everything that attempts to enter Router 2. Or should DDNS take care of that?

My boss is saying buy a new fibre router...I asked him (he's got like 10 year network experience at high level) and he's saying anything  blocked by the first router will not be passed any further down the line so either you find a way of turning off the UDP reservation or totally bypassing it or you'll just need a decent fibre router.

Thanks, that's what I suspected.
