PIX 7.0 is tentatively scheduled for the January timeframe. This is not yet committed as we just entered the beta release. Talk to your local Cisco account team if you are interested in participating in the 7.0 beta release.
I have heard 100 vlan's with 7.0. Is that true for the 525? I know we have a limit on physical which is not the point. I talked to the cisco rep yesterday and this is the info I got. Can you inlighten?
For the UR version of the 525, we are indeed targetting the support of 100 VLANs. This is subject to change until we get the final release but at this time, all indications look good for having these max number of VLAN's.
