Cisco 837 pass all traffic

Tags: cisco, 837, telnet, traffic
We have a Cisco 837 router and a single IP address from our ISP.  Behind that, we have a Draytek 3300 security router.  I want the Draytek to handle EVERYTHING other than port 23 for external telnet access to the 837.

I could get another IP address from our ISP and program that into the Draytek WAN port... but it would be quicker if I could tell the Cisco to pass all traffic on all ports to the Draytek, except for port 23 so I can maintain telnet access to the 837 for reboots.  As I'm working on the device remotely at the moment I'd rather keep telnet available so I can reset settings if I have to - I appreciate that's a security hole.

The 837's internal IP is 10.0.0.1 and the Draytek WAN port is 10.0.0.2... is there a simple set of CLI commands I can run in to configure the Cisco?

Thanks

The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.
