[Dxspider-support] Incoming telnet connections getting blocked after about 30 minutes

[Dirk Koopman]

Mike

It certainly seems to be a Huawei thing. I use a RPi 3b as my router 
running OpenWRT. I have the NIC facing "home" and another a usb 
connected NIC facing the PPPoE modem supplied by BT. I believe there are 
a few OpenWRT  compatible routers that will plug in to the microfilter 
directly or you can buy a VDSL2+ -> PPPoE modem from Amazon.

Who is your internet supplier? It may be that they have a "policy" about 
not running servers on the end of ADSL connections. In which case 
complain and/or change your ISP. I use and recommend Zen.

Good luck

Dirk
