How to secure public router

jilahbg · ‎11-11-2003

Hi

I have to place a 1721-router outside of the firewall. Which are the best ways to secure the router? It will have public IP:s on both ethernet-interfaces, it will just route IP, no other functions are needed in the router.

Turn of SNMP.

ACL to control telnet-access.

What else?

Thanks!

Jimmy

Check out the book - "Hardening Cisco Routers" by Thomas Akin. O'Reilly press ISBN 0596001665. It has some very simple and also lots of cunning plans to secure your network devices.

I am always happy to check out any freebie. The document that you pointed us to contains a reference to the book that i suggested in paragraph 3.5.1.

I like your freebie answer better than my suggestion of spending money.

Cheers
