Over the weekend, I was asked to help roll out IPv6 for hackerspace.sg; they had a TP-LINK TL-WR.* running openwrt that they were trying to set up, so they could provide one wireless ESSID for IPv6 and another for IPv4.

They had gotten access to the 881 courtesy of M1 not wanting to help them debug 6in4 issues. After verifying that M1 wasn't filtering packets, I set up a Hurricane Electric IPv6 tunnel on the 881 and added an EEM TCL script to handle the public IP change.

Openwrt on the TP-Link seems to do well, the modularity certainly beats the license raj known as cisco. Especially when you can just add a USB disk and now the TP-LINK works as a multipurpose linux-based server.
So now Hackerspace.sg has an extra TP-LINK and I got to use TCL twice in the same weekend.
