Hi All

I have customer which has purchased an 1841 modular router with a SDSL wic & a ADSL wic and a 1812 router to establish a VPN connection to the 1841 from a branch office. The ADSL wic will be used by internal clients at HQ in a sbs (1 nic) network for internet and email. The SBS box requires ports 25,80,3389 (and a few more) to be redirected to its single nic. The SDSL wic will used for hosting VPN traffic only. The VPN connections will come mainly from the 1812 router based at a remote site. Also VPN connections will come from MS Win XP PPTP clients and draytek routers using 3DES.

A config file for the 1841as follows:~

 

SDSL WIC

*      SDSL Internet dialup setup
*      SDSL wic public ip address to be set to 82.82.82.1
*      Incoming VPN connections from several locations

network

ADSL WIC

box
*      Allow sbs box to received traffic on ip 123.123.123.2
*      Allow sbs box to appear to send mail for 123.123.123.2
*      Allow a  internal web server to received traffic on
123.123.123.3
*      Allow telnet
 

A Config file for the 1812 as follows: ~

*         Setup a public ip address of 90.90.90.1
