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!
