Cisco 1841 need to open PPTP and RDC ports

I have a Cisco 1841 router.

I need to open PPTP (1723) and RDC (3389) so that I can access my servers from the outside.  I tried adding some NAT and ACL rules but it did not work.  This router is also connected to another office with a VPN which I think complicates the issue.

Should I create a new ACL or add some lines to an existing one?

I only have 1 public IP address and all other computers on my LAN use that IP through NAT.

I want to open PPTP to 192.168.33.33 on the LAN side.

I want to open RDC to 192.168.33.34 on the LAN side.

My configuration follows.

Re: Cisco 1841 need to open PPTP and RDC ports

where do you want to pptp from and also where do you want to RDP from

what i mean is i know where you want to get to, but from where do you want to get there

Re: Cisco 1841 need to open PPTP and RDC ports

I want to RDP and PPTP from ANY public IP address, through my WAN connection

Cisco Employee

Re: Cisco 1841 need to open PPTP and RDC ports

you need to allow this in out to in policies, you need to do the following

class-map type inspect match-any pptp_rdp

match access-group xxx

policy-map type inspect out_in

class type inspect pptp_rdp

  inspect

zone-pair security out_to_in source out-zone destination in
service-policy type inspect out_in

in you access-list xxx match any to private ip on the requirement ports

ip access-list extended xxx

   permit tcp any host eq 3343

    permit ip any host eq 47

i am not too sure of the syntax for acl with port s but i think this is what it is

Re: Cisco 1841 need to open PPTP and RDC ports

ok, I managed to enter everything except these lines:

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

zone-pair security out_to_in source out-zone destination in
service-policy type inspect out_in

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

I get this:

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

CCP-SF-1841RTR(config)#$ecurity out_in source out-zone destination in-zone
% Already zone-pair sdm-zp-VPNOutsideToInside-1 exists for the specified source
and destination zones

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

Please look at my config and let me know what commands I should be using here.  Since the zone-pair already exists, should I be adding the service policy to it?

Is it possible to do any of this with SDM?  It doesn't appear to let me edit anything.
