I bought a 3com 3crwe554g72 and when it connect with my ADSL modem the speed will become very slow (-50%). I update to the lastest firmware but no help

3com used to be good things back in the old days. But this hardware is probably self destructing in some way (the problem is widespread, the manufacturer claims it is an old product and gives no solution). Do NOT buy network products from 3com (HP today). Correct me if I am wrong..

Configure VPN

That 3Com really doesn't have a wahy of setting up a VPN.
As per the 3Com site it:
Support of VPN termination/initiation and passthrough allows secure connection to central office and/or secure access from remote workers.
So it will allow 3rd party VPN setups to pass through, but it doesn't have the ability to create one.
You might want to look into something like a Netgear Firewall
