Re: [TCLUG:19111] Cisco 675 and my network...




Bummer. Cisco finally did the packet filtering "correctly" in that release,
based on the release notes. That release finally lets you block a range of
ports with a single filter rule. Imagine:

0) allow all 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 dest-port 80
1) deny all 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 src-port 1-65535 (or whatever
max is)

Lock it up tight, I say...

Nope - my ISP (VISI) will not support 2.3.5 currently.
