THANK you for answering!

speed is the main criteria ,with security

i think i can manage .do you think of other things?

Hi

It really depends. For example a router would run the firewall feature set although if speed rather than security were your number one priority you probably wouldn't be interested in this.

A 3750 can't do NAT whereas an 1841 could.

Just wouldn't want you buying something that didn't meet all your requirements :)

i have 1841 in the wan and 3750 in the lan

if i need nat it is for external networks

and that could do the 1841

i understand what you mean thanks for your concern
