Re: (ASCEND) Ascend TNT and large IP-Pools

[Steve Meier <steve@gigabell.net>]

Hi Oliver,

we are experiencing the same problem with our TNTs. :(

As far as I know the fact is that there is no way around that in
Ascend's TAOS
releases 7.x.x. I've read that there is a so called pool-chaining
feature in TAOS 8.0.0+
which should solve that problem but I haven't tried that yet although
one of our boxes is running TAOS 8.0.0.

I would greatly appreciate any comments on that. :)

Steve
