About a month ago (maybe slightly more now) my gateway stopped working
correctly. It had been running without issues for about a year.
I'm using a Ubiquity erX running ampr-ripd, using Marius's directions
on the wiki. (BTW, ampr.org looks to have a php issue at present)
The erX was connected directly to my modem. Since then I have rebuilt
the setup a few times after it stopped working correctly. Currently I
have two erX's setup. Modem -> erX (DNAT protocol 4 to LAN IP) -> AMPR
erX running ampr-ripd. This way I can mess with the AMPR settings
without annoying the rest of the household!
On the AMPR erX I have 729 routes showing.
44.68.180.14/32 is my tunnel IP
44.68.180.1/28 is erX eth port
traceroutes to these two seem to work correctly.
traceroute to 44.68.180.1 (44.68.180.1), 30 hops max, 60 byte packets
1 gw.k1ymi.ampr.org (44.68.180.1) 159.637 ms
But to 44.68.180.2 & 3 (linux box & JNOS)
I have '-a 44.0.0.1/8' in the ampr-ripd shell script. I have also tried
adding my /28 in there too.
If I have my subnet in the ampr-ripd config the traceroutes try and go
through n2nov's gw in a loop.

If I remove my subnet the traceroute goes nowhere.
Does anyone have a suggestion as to what I am missing ??
