Proceeding with debugging, I'm getting even more close to the problem but still need some help. Giving to OpenBSD box a local IP, and accessing from a same-subnet IP machine, I get full speed (about 8 MB/s downloading). Problems come when I give to OpenBSD box an IP of another range, that goes behind a Cisco router: downloading from the same machine (and adding a hop in the path, the router itself) only reaches 20-30 kB/s, while giving the same IP to another linux machine and getting a file with apache2 reaches 150 kB/s. Any idea?
