Just to quick check here.
Anyone here configure their router as VPN server?
I have try configure as VPN server and DDNS using no-ip.com and I'm using Time Dot Com for my router and phone using celcom.
On the router setup, enable VPN server - PPTP, MS-CHAP-V2, MPPE-128, No - broadcast traffic. Then user setup to local ip to 192.168.1.245-192.168.1.254
Some how I can't connect from the client, from my android phone to my router via. celcom -> Mi-Mini Router (no-ip.com ddns).
I also have try with direct ip addresss.
I managed to configure my main router Mi-Mini to allow ftp, sftp, ssh, smb and also port forwarding to another Mi-3 router and android box with both running ftp, sftp, ssh and smb too.
No problem accessing them from internet (from phone or office wifi) including web gui from my Mi-3 router.
Dunno why it fail for VPN server. Any expert here can help?
There were a bunch of them...I ended up recompiling today...some may address your issue. Previously 09/24 was last commits showing so 10/16 onward were new and pushed in last couple of days. You can also monitor the open issues to see if your issue has been reported or open a new one. Keep in mind he provides ZERO support for the xiaomi version however if it's a general padavan issue he'd probably still address it. The padavan author is NOT the same person who wrote the prometheus script however the prometheus author DID have permission from the padavan author to do so.
