Any body please help. :slight_smile:

can you traceroute or ping from the router to the internet via ppp tunnel?
Please upgrade the RouterOS to the latest version - v6.7

4

so far i can not ping or traceroute via ppp tunnel.
upgrade will cost me money even I don’t know whether that will fix the problem or not :confused: can I try that in VMware so I can test if that works or not ?

Upgrades are free, but check compatibility with your 3G modem

ok I tried by updating still same issue.

UP UP ^^^

Hello! I have some troubles with ppp also…
When I turn on MT all works fine, until I try to login to web page… As far as I try to login ppp RX stays 0 so no Internet connection.
The interesting thing is that scanning from the outside WAN IP gives:
Starting Nmap 5.21 ( http://nmap.org ) at 2014-02-04 10:36 EET
Nmap scan report for 188.69.xx.xx
Host is up (0.027s latency).
Not shown: 999 filtered ports
PORT STATE SERVICE
21/tcp open ftp

it is strange . I cannot acces managment either per 80 or winbox port but it claims that 21 PORT is open
what is more… watchdog script that pings 8.8.8.8 does not restart the router. but I cannot ping 8.8.8.8 from LAN side
