Posted September 16, 2013 By Landis Vstack your knowledge: IOS IPsec ezVPN server – part I
Posted September 11, 2013 By Landis Vhttp://staystack.blogspot.com/2013/04/ios-ipsec-ezvpn-server.html
Helpful article, though I wasn’t working with ezVPN. The ‘reverse-route’ component was a critical one I was missing, though I’m pretty sure it’s still not going to get me where I need to go. I’m attempting to get a software VPN client configuration to work with a router that’s also performing IPSec VPN in conjunction with VRF and zone firewall. We’ve already encountered one show-stopping bug between ZBF/ZFW and NAT virtual interface (NVI), and I’m fairly sure about five steps down the road from reverse route injection that we’ve encountered yet another bug that will prove fatal in this endeavor as well.
No matter I guess. Probably need to get this lab back to a more standard configuration in any case. If you do happen to encounter a problem with ZFW, VRF, and software VPN client I’d love to hear about it in the comments. Always nice to know you’re not the only one Cisco’s feature sets are leaving up a creek. If I get time, I’ll try to post a more detailed configuration example and steps that lead me to this conclusion. I still haven’t completely disproven it, and haven’t run any debugs at all yet, so there’s still a slim possibility it could actually function.
Multi-IR remote
Posted September 1, 2013 By Landis VThis, possibly in combination with this (or at least the software component thereof), might be a simpler solution to something I was thinking about today. I have an XBMC remote control application on my phone and tablets which I like for several reasons. It’s always handy and never lost – or at least easily found – are among the top of these. This got me thinking about running an IP-to-IR remote so I could leave an IR transmitter in some fixed location always pointed at remote controlled electronic devices, and just use my always handy Android to manage channels on all the devices. As an added bonus, the webmote software might provide an option to integrate all the remotes into one single control interface rather than needing different remotes for TV, DVD player, surround sound, and XBMC.
My original thought was just to figure out a way to integrate a USB port on an existing remote control and basically trigger the sending of the commands, but this would probably be more universal and likely much less thought and work intensive.
I found ATmega 88’s here for around $3 each, but haven’t reviewed the full parts list yet.

Serving multiple DNS search domains in IOS DHCP

DHCP option 119, though having to convert to hex and null-term is a PITA. If it does what’s needed, then probably worthwhile.
