I'll soon be building a VPN between two locations of a small company. The main location uses fully open ADSL while the second location uses cable (residential service due to lack of alternatives) to access the net. This cable connection has its tcp port 139 filtered at the upstream router. I've read a few articles on VPN using IPSec on FreeBSD and I think I'll manage setting this up for mail and the like since those ports are unfiltered. The articles however don't mention any restrictions on either end of the pipe and how to deal with such a situation. I'd like to be able to have my Windows network clients browse and use resources on either side of the tunnel. With tcp port 139 being filtered on one end, and my ISP unwilling to remove the filter, I'm worried. Is there a way to circumvent this? Should I redirect port 139 to some high port between the gateways? My servers are all FreeBSD (4.5 RELEASE) running Samba 2.2.2 so it's possible to set the listening port differently on them, but will my Windows 2000 clients be able to adjust their ports as well? I've read something about changing lines in an inetd.conf-like file called 'services' inside Windows' main directory, but I have no such file. Should I create it myself and have it contain only exceptions from the defaults? Any help on this subject is very welcome. Thanks in advance, Bas v.d.
