I need to choose a processor for a router (like) box.

Here are the requirements:
-=A0 must run Linux with vpn (OpenVPN), http (Apache?) and possibly ssh (Op=
enSSH)=20
- 3 PHY interfaces at 10 Mbit/s=20

Users will connect to the LAN through a secured VPN, and there will be at m=
ost 10 users. Traffic will be limited to 10 Mbit/s even if the MAC+PHY is c=
apable of more.
It is required to keep response times below 10 ms at all times.

Since I do not have any experience in this field, I=A0 ask your opinion on =
this subject. What would be a good micro-controller and mac+phy choice?=20
Shoudl I opt for something that has 3 different MAC's or for something with=
 1 MAC and a switch chip with VLAN support (will this be enough?).=20

Qlwo what is more suitable for this task? ARM based, MIPS,=A0 PowerPC or so=
me other micro? Personally i lean towards MIPS, tends to perform better in =
case of such tasks and from what I've learned is more Linux friendly.

Let's say I go with MIPS, will a 24KEc at 480 Mhz be enough or do I need so=
mething more powerful?=20

Any help is much appreciated.
