I feel you are incorrect in stating that 3COM Netbuilder II routers
can not be used as firewalls or as part of blocking router for a total
We use a 3COM routers as a firewall to protect certain parts of the
Midas project and it also used by many school districts in California.
3COM routers, in my opinion, are easilier to setup and maintain than a
Cisco routers. They are also much cheaper. Any Netbuilder router software
release after 7.0 has filter lists similiar to Cisco access lists. Any release
after 8.0 has increased filter performance to very good. AS a firewall router
I feel I can do anything with 3COM that I need to do.
(I have used both CISCO and 3COM) There is no doubt that Cisco sets
the standard for TCP/IP routing. They are usually the first out with new ideas
(first major vendor with compression on frame relay) Bay Networks and 3COM
added it in the next release. Cisco 7000's has logging which 3COM Netbuilders
lack at as time. There are many pros and cons to both vendors.
Bob Konigsberg at 3COM has written an excellent article on using 3COM
routers as part of a total firewall solution. Really worth reading. I would be
happy to provide an eMail address to receive this article if you are
Lastly, I would be happy to provide some information on filters, etc.
about 3COM routers if anybody is interested.

firewall problems there !! I could never get my laptop to work with the local

ObAdvise: Don't use a 3Com router as a firewall.
