How would an intel j1900 cpu perform compared to mikrotik hardware (450g/850gx2/ccr)?
Or any modern intel cpu with passive cooling.

I neet the eoip tunnel because i want the same broadcase domain.

I'll probably evolve toward ipsec later, but for now i want to use pptp (it's easier to setup).

Do you mean to bridge pptp connection to eth port on MT?

BTW. Toward what value sould i set MTU? On pptp connection or eoip connection?

Re: wireless docs

with 5ghz i've managed a steady 20mbps tcp transfer.

on 2.4 i've tried the 13 channel (2472) because there are no conflicts here (based on inssider).

using btest from MT, tcp, both ways, i get ~1mbps, ccq under 10%, signal -45dBm, snr 56dB .

i'll try and investigate tomorrow.
