Biggest problem was distance and turret range, and to be able to trigger an attack from the turrets, because they act like some well stoned treehuggers were controlling them.
I even added some prod modules and an admin module to it, maybe that helps attracting enemy attention.
So this is how it started, took a plot, placed it as close to the gate as i could. Once placed i could rotate and expand it so it just touched the gate.
Did cost a couple millions since it's "close" to a gate, but build cost is 250m anyway so that's just the change (hi Taraktas by the way


Then i built this layout, with the intention of trapping incoming traffic between the turrets.
AI pathing is surprisingly good, really good job from ES on that account - if the ship has a destination past the other exit of the tube it will happily fly through without issues.
Sent a fleet of 10 capships through it back and forth, they only had minor issues when destination was behind or to the sides of the gate - but still then they managed after some slight hugging.
That was a surprise for me, as the shape is not really convex



I tried putting lasertowerers inside to trigger the turrets, but those will get moved outside the tube once i leave the sector, and the same happens to ships i just leave in there - so not the best approach, but then i realised i could build a couple M docks inside and park some gorgons in there with 4 upward facing turret set on attack all might just do it.
You can see an Ody just passign through without problems below onthe right.

So far the gorgon trick seems to work:

Then i just set there felt like i'm a fat spider in its web waiting for those stupid insects..
First little one arrives while still under construction - had a feeling already i had overdone it during design phase, but i wouldn't let that hold me back, i wanted a tube for real..

Then a P got caught in my laser web, promising...

This K lasted about 5 seconds, hardly had enough time to close the map and take some screens of it.. think it had some unrealistic plans regarding my construction ship



This buid plan xml contains the layout, gate defence final is the full structure which can be moved around easily (the handle is a defence bridge in the bottom). It has no docks inside, but can be easily reused i think if anyone happens to need this stupidity in their game..
Once placed all the connection structures can be removed, and probably 60% of the defence modules as well as it's effective enough judging from the Ks short and sorry end in my web.
FPS for me is 25ish when there is no fight, and cartoonish when the turrets go live. But a 3rd of the modules should be enough, will post again once i catch an I finally - but don't think it would last longer then 15 secs.
HOP has built 10+ stations in xenon space right on the other side of the gate so it takes a while until i get to feed..
Must really love the game if/when it works. Pity there are so many issues, but partially it was my fault this time i guess as it's not entirely the intended way to use.
Funny that this absolutely not intended thing with kissing the gate seems to work finally.
