[HamWAN PSDR] Metal 5SHPn firmware 6.12 is current (addendum)

[Nigel Vander Houwen]

Dean,

I'll answer both your emails in this one. RE the first email concerning route cache with l2tp tunnels. We saw that and have tested it on Bart's and I's uplink modems and it has not fixed the route cache issue for non-l2tp tunnels, this is confirmed by the forum ports.

The mangle rules are not related to ovpn. The issue is that the uplinks have connections (public ISPs) that limit to an MTU of 1500, and the ipip tunnel with ipsec takes up some of that for the headers, so packets must be mangled to be smaller than that to pass through the uplink nodes to and from the internet correctly.
