Hi,
In trying to migrate HamWAN to IPIP anycast as discussed in a previous thread. I have run across a problem at the very last step. The relevant screenshot is at http://imgur.com/X2BfziT . Cannot attach the PNG due to message size restrictions.
Basically, when I try to change the Gateway IP for our 44.24.240.0/20 subnet to be 44.24.221.1, I get the error message "Invalid gateway IP address".
I'm sure this was intentionally coded at some point, but I believe this to be a design error. Here's why:
1) 44.24.221.1 is outside the associated prefix list for this gateway (44.24.240.0/20 only). 2) 44.24.221.0/24 will not be configured to have an IPIP gateway as it is being announced directly on the Internet.
Given those two conditions, anyone with traffic for 44.24.240.0/20 can send it via Internet or IPIP to 44.24.221.1. When sending to 44.24.221.1 (outer IPIP header dst-addr), there should be no conflicting route and the default route should be taken, resulting in proper packet delivery to HamWAN.
Can someone add this gateway manually and then fix the portal interface problem?
Our tunnels are re-configured into the new desired state and awaiting packets. :) We are presently in AMPR tunnel downtime mode until that gateway is set + propagated.
Thanks!
