Protocols for Win VPN pptp in ACL

pwolsza_wolfik1
Level 1
Level 1

Hi

I made configuration to connect computers using the windows VPN client with set PPTP  on the router and MPPE encryption.

Using this:

http://www.cisco.com/en/US/tech/tk827/tk369/technologies_configuration_example09186a00801e51e2.shtml

Now I have a problem with ACL.

Which protocols must be opened on outside port ??

I'm using C 871.

My configuration:


Current configuration : 9906 bytes

% Password expiration warning.
-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for  one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you
want to use.

There is no such site

Apologies, that link required login.

Try this instead :

Regards,

This tutorial is very useful.

Unfortunately on my router there are a lot of already configured ACL rules.

I do not want to destroy something what works perfectly, I just want to add some rules to allow connect through l2tp and to ping server which is inside.

All the rules was made using automatic creator in CCP.
