[cisco-nas] l2tp sessions to an 1841 and radius authentication

[John Ward]

Hi, i have been playing with an 1841 running 12.4(1c) IP BASE code and
have it running quite ok.
The issue is that i have some sort of limit on the number of
simultaneous tunnel connections to the 1841.

Once i've hit 15 sessions, it wont let any more onto the router.

it is funny that it is 15 sessions exactly. Almost like a hard IOS
limit on the feature set.

Memory shows 77MB with 12 used and 64 free.
the new connections connect, then simply disconnect and so it goes on.
If i kill a few tunnels, then those that couldn't join, join and teh
ones that have been reset cant.

Question: what image/feature set should i be using for about 500 low
bandwidth l2tp tunnels ( roughly 5Kbit throughput) as i cant seem to
find any documentation on this.

The only document i find is one which just says that the router can
handle 500 or so connections ( i would imagine at a push with the wind
blowing in the right direction, and if you have cheese on your bread
;) )

Here is the only document i can find with the specs of the routers and
their tunnel capacity.
