As promised I will report back... My test was concluded after only 167MB of random data: $ scp testbox:testdata /dev/null testdata 83% 167MB 0.0KB/s -stalled - Instead of my AP, I used an available FreeBSD box with OpenSSH 4.5p1 as remote endpoint for the tunnel -- the problem didn't disappear. The testbed: Laptop <--WLAN--> AP <--LAN--> FreeBSD box <--LAN--> Internet I think I will drop it now and look into IPSec or OpenVPN. That way I will also avoid TCP-over-TCP problems. I am pretty sure that it isn't TCP-over-TCP problems that I am fighting against in my ssh-based VPN setup, as my ssh control connection doesn't die -- only the tunnel device forwarding part. Not only are the connections through the tunnel stalled, it is also not possible to establish new connections through it. Martin
