I have D-Link 604 router which was provided by my service provider then I have Linksys Broadband Router.  I want to use VPN and RDP on one of my computer, which connects to Linksys router.

IP for Linksys: 198.168.1.1
IP for D-Link Setup: 198.168.0.1
IP for the computer which I want to connect is: 198.168.1.102

When I try to enable DMZ on DL-604, its giving me only one option 192.168.0.?, where ip for my comptuer is 192.168.1.102

You need to turn the d-Link604 into a bridge and setup the WRT54G as the firewall/router.

----internet---------d-link604(bridge mode - no ip address)-----------------<WRT54G>-----------------internal

Check the D-Link site for how to do this with your product.

Alternatively if this is not an options and you still want to do VPN on the WRT54G you will have to have the following three ports forwarded from the D-Link604 to the interface of the WRT54G router.

esp all
isakmp udp port 500
isakmp udp port 4500

Apologies.

The D-Link 604 is a broadband router, Why do you need both devices.  Replace the D-Link604 with the WRT54G.

I am not able to replace D-Link604, with the WRT54G because Verizon have setup default information in D-Link and they are not give that to users.

I know the username is Verizon but dont know the password. I tried to replace Router it won't work.

Thanks

Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

You will have to configure port forwarding then.

Using your current config use the following example:
IP for Linksys: 198.168.1.1
IP for D-Link Setup: 198.168.0.1
IP for the computer which I want to connect is: 198.168.1.102


LAN-----------<192.168.1.1>Linksys<192.168.0.2>-------<192.168.0.1>DLink<xxx.xxx.xxx.xxx>-------internet

 - To connect to <192.168.0.102> on your LAN you will need to add the following rules:
DLINK====forward from any source ip on port 3389 to 192.168.0.2
LINKSYS=====forward from <any source  ip> on port 3389 to 192.168.0.102.

This will allow you to RDP to the address on your LAN behind the Linksys from the internet using your internet address <xxx.xxx.xxx.xxx>

The same will be required to get the VPN working although you will have to forward all traffic for the following:

- esp any any
- isakmp udp 500
- isakmp udp 4500 (just in case it needs to do NAT-T)

I am accepting your answer because when I try to get rid of D-Link it worked, previously it was not working because of Setup I have set it as PPPeo.

If possible for you let me know what port I have to open for RDP and how. I did opened 1723 for VPN.

Thanks
