Customer-facing ACLs

Wed Mar 12 02:57:25 UTC 2008

Those ACLs were added when I came on board.  Again, only one complaint in 3+
years.

And customers wonder why I shudder when they tell me that they plug in their
Win9x computers directly into their cable modem.  I can't imagine how much
worse it would be if I didn't block the SMB ports.

We have a two-dozen line long ACL applied to our CMTS and BRAS blocking
Windows and "virus" ports and have never had a complaint or a problem.  We
do have a more sophisticated residential or large-biz customers ask, but

I'd like to ask the same question of you that I just did to Chris.  How'd
you implement that or has it been there since the network was new?
