Hi Vadim,

while playing with fake_trx and trxcon I was wondering about the port
numbers you used.

I think it's not the best idea to re-use the same port numbers / port
number range on the MS side which are used on the network side.  Is
there any requirement to do so?  why not simply shift the entire base
port (5700) on the client side to something else like 6700?

(Side note: The entrire TRX protocol using so many non-standard/non-IANA port
 numbers, not containing any version numbers for extensions, etc. is a mess,
 but that's for a separate discussion altogether.  Would love to re-do
 this from scratch at some point)
