Performance trouble on OfficeConnect Internet

[epigeon]

Hello,

I own a 3Com OfficeConnect Internet Firewall DMZ (3C16771).

There is actually 5 VPN distant sites who get connected througt this router. Approximately 50 users are using Terminal Server (Windows).

Here is what i read on the admin panel of this router :

Firmware version: 5.1.6.0


ROM version: 4.0.0


CPU: Motorola MC68360 / 33 Mhz (DMZ)


RAM: 4 M


Flash: 2 M


Ethernet Speeds: WAN 10 Mbps Half Duplex, DMZ 10 Mbps Half Duplex, LAN 10 Mbps Half Duplex


Current connections: 190


 

Current connections may vary and sometimes go up to 300.

We get some lag when using TSE and i'm asking the following question : is this 3C16771 can support all these connections ? / there is a 2Mbps internet connection.

Second question, i can't find any SNMP system on this router, is there any solution to monitor it ? (bandwidth, number of connections, ...)

Thx in advance.

Regards,

Edouard
