Just got my first routerboard and I would like to use it for HE IPv6 tunnelling. I’ve found various tutorials and examples so don’t think I’ll have too much trouble getting a tunnel up and running but have one issue which is that my public ip is dynamic. It hardly ever changes but I need to allow for it as if not I’ll typically lose remote access just when I need it.
I found a good example of how to handle this elsewhere in the forum (http://forum.mikrotik.com/t/6to4-tunnel-with-tunnelbroker-com/33877/1) but my issue is that the routerboard won’t have an interface on the public internet - it’s going to be in a DMZ connecting out through my ASA. The ASA will process my ddns updates on the tunnelbroker.net side of things as well as no-ip and gandi (for IPv4 glue) but I have no idea how to get the routerboard to detect and update the tunnel configuration if my public IP changes.
Any pointers on how I might achieve this? As I said this is my first time using a routerboard so please be nice.
Why not just use the routerboard as my gateway device? It’s useful for me to work with the ASA as I often encounter them at work. By putting the routerboard in my DMZ with a second interface connected back in to the asa as an outside zone I hope to be able to simulate a native IPv6 connection so far as the ASA is concerned. I plan to use the allocated /64 for the hop between ASA->RB and then the /48 for my internal network zone. I think this will all work but there’s only one way to find out.
