Access list to allow VPN requests to a VPN Server

Hi,

I am replacing a client's diginet line with an ADSL. Currently they have static public addresses assigned to servers which are obviously reachable from the Internet. These servers are used by clients to make VPN connections to.

I need to do the following:

--------------------------

- Remove diginet and replace with ADSL

- Remove the 1721 and replace with 877.

- Remove the static addresses and add the servers to dyndns.

The VPN server is a windows server. Their mailserver is a linux box. What would the access list be to allow the VPN requests to the windows box and to allow the linux server to still do email?

I can add a permit any any statement for ssh but that is about as far as i got....what next?

thanks

Re: Access list to allow VPN requests to a VPN Server

VPN servers use standard TCP port number 1723 for PPTP and emails use port TCP 25 and TCP port 110.So an extended access list could be configured with these options.Refer URL
