Maximum number of connections

[Tellus1]

What is the maximum number of concurrent TCP/UDP/etc. connections this router can handle - with either firmware?
Have there been any cases of router freezing (on heavy use) reported?

Practical limits for 16MB RAM is about 2500 connections.
You can see the count per IP with

sed -n 's%.* src=\(192.168.[0-9.]*\).*%\1%p' /proc/net/ip_conntrack | sort | uniq -c
Free RAM can be obtained by command free
