Hello Sir/Madam,
I cannot access our VPN from the internet outside our organization. I am using Cisco 2610 Router with IOS v12.3.
And i created the access-list for the inbound and outbound connections. I have mentioned the access-list below and also i mapped a static IP address with the VPN server's IP so it can be accessable from outside.
The access list is
>>access-list 105 permit gre host 203.200.20.94 any
>>access-list 105 permit tcp host 203.200.20.94 eq 1723 any
>>access-list 115 permit tcp any host 203.200.20.94 eq 1723
>>access-list 115 permit gre any host 203.200.20.94
What is the exact configuration has to be made on the router and the server..
Please help me...
Thanks in advance

Hi Parame,
I believe your acl 105 is input acl at inside facing interface of router. In that case, you cannot use 203.200.20.94. You have to use real IP address of server. NAT operation hasn't occured when router check the input ACL yet. Please see this link from Cisco.

Tip: If you are in doubt, apend "access-list xxx deny ip any any log" to acl and watch your log to see whether your legit traffic has been blocked.
