Every time I reboot my Cisco IOS 800-series router, all the Windows 7 machines 'identify' the wireless network as being a 'new' network, forcing users to classify it as Home/Work/Public all over again (and more painfully, causing host firewalls to th...
My client would like callers who have dialled an extension and been put through to voice-mail to be able to return to the site's operator instead of leaving a message.I thought to callf-forward callers to an AA script instead of to the 'voicemail' ap...
I've frequently seen recommendations to have a separate "management VLAN". I guess the main ideas are:a) to keep managment-traffic and data-traffic out of the same Layer 2 broadcast domain? (So that rogue stations in the access-layer can't sniff ma...
Is minimising one's use of the private address space to avoid unnecesary potential overlap worth the hassle of having un-even VLSM lengths?I am designing my first non-trivial IPv4 addressing scheme in the 10.0.0.0/8 range. Just two small branch offi...

I have found a problem with option B1. If I'm on R3 and try to ping R1, R1 has no route back to me, since by default the 'ping' command will use the interface nearest to the destination, and will thus us its IP address in the /30 address as the src ...
Hi Joseph, that's a useful example, thanks. In particular, the setting of the source-interface for the SSH server, etc, was something I hadn't picked up on before. Also how the switch defends itself with the 'IPV4-MANAGEMENT-ACCESS' ACL - solves an...
