I have fixed this already in Wagon 3.2.0 in WAGON-486. Use a Maven version which has this builtin. It should fix your NAT problem.
Reread the tickets, my explanations were very detailed.

Hi all,


I'm sorry for reposting this[1]. But I'm sure there is someone in this 
community who could inspire me to fix this. We are still seeing a lot of 
stalled Maven builds on Bitbucket, and we don't know anymore what to do about 
it, besides moving off of Bitbucket (which we've talked about... red tape). 
Your help would be much appreciated!!!

Best regards, Sander.

Hi all,


Need some help! My current gig is running its Maven builds on Bitbucket. On a 
regular basis, builds stall while downloading dependencies (I'd say 5%~10% of 
all builds). It looks a lot like [1]. The proposed solution 
(maven.wagon.http.pool=false) does not show any noticeable improvement. 
Atlassian declined to investigate, even though this only ever happens on 
Bitbucket (local builds have never been seen having this problem).

I have included some logging (-X) from just before the stall. The stalls can 
happen anywhere dependencies are downloaded, so seemingly unrelated to this 
particular goal.

I would love to get some suggestions on how to fix this, or at least on how to 
troubleshoot it further.

Thank you!
