Hi

I have set up pptp link in RIP routing between my lab mt 750 routers. After configuring the pptp link , and I enable arp-proxy so i can ping and have connection on the local lan PCs. I can ping and tracerout ok, the interesting thing that i want to know is that even when i don't ping or tracerout the is some activities on the PPTP link.


I want to know what kind of activities on that PPTP link are happening ,that is:
- what protalcals are using the pptp link
- what services send/receive data on that link,
- who sends the data what address

Is there a tool in MT to check this? if yes how to configure/use the tool?

thanks

Hello

PPTP use TCP port 1723 for connection establishment and use GRE Protocol (IP protocol ID 47).
PPTP is using for layer 3 communication so you can use layer 3 protocols on that link.
You can use Torch tools to see what was send or receive on your Link.(right click on your PPTP link and select torch)

Good Luck

Thanks, i did, and i was having 2 winbox connections. upss. lol

Not sure what you're using PPTP for - but you should know that the encryption is now conclusively broken - really, really, really badly.
Anything using MS-CHAPv2 [or any version of MS-CHAP really, though we already knew CHAPv1 was bad.] is horribly broken. Use something else.
