Yep, you just have to replace the interface names (vr0 -> sis0, vr1 ->
sis1, etc.).

do not get any further than about 6,000kb/s.  The line has a max of 20,000kb/s and when I put the
Wrap back on line I get about 17,000kb/s.  I think something must be wrong but I have no idea,
especially as both configs are the same.  Can anybody help with this?

Any errors on Status->Interfaces?

What type of WAN connection?

Haven't seen any issues on 4 I now have in production on 1.3b9 in a
variety of environments.

> And a last one: What is the better way to go, use interrupts or device polling on Wrap and Alix?

Depends. Polling is slower, but it also ensures the interrupt load
will never make the webGUI inaccessible. Under very high load without
polling, the webGUI won't work. With an ALIX it'll be hard to get it
up to that kind of load (talking 80-90+ Mb likely, I haven't yet
tested to see exactly).

I run all my ALIX boards without polling, but if they were in
environments where they could see 80+ Mb loads I would consider
