Teliax Down?
Is anyone else experiencing trouble with Teliax? I can only intermittently
register to, and am not able to place any outgoing calls through my assigned
gateway; voip-co3.teliax.com.

Simplify simple code
Dear expeRts,
I would simplify following code.
---------------------------------------------
youtput <- function(x1, x2){
n <- length(x1)
y <- vector(mode="numeric", length=n)
for(i in 1:n){
if(x1[i] >=5 & x1[i] <= 10 & x2[i] >=5 & x2[i] <=10)
y[i] <- 0.631 * x1[i]^0.55 * x2[i]^0.65
if(x1[i] >=10 & x1[i] <= 15 &

Arimax with intervention dummy and multiple covariates
...b. To facilitate the specification of the various models (the different model specifications dropped variables or added additional covariates, etc, without changing the general structure of the syntax below), I defined the following design matrix:
> xreg.1 <- model.matrix(~CO1+ CO2+ CO3+ CO4)[,2:5]
c. Following Cryer and Chan (2008, ch. 11, p. 255), I wrote models such as this:
> arimax.1 <- arimax(VI, order=c(0,1,1),
+ xtransf=data.frame(xreg.1,dummy1=DUM),
+ transfer=list(c(1,0),c(0,0),c(0,0),c(0,0),c(0,0)))
d. So, I get estimates for the following coe...

Routing or Nat question

I used to have a xDSL with a Cisco 677 router setup that connected via
PPPoE to my ISP.
I now have a different ISP that uses a xDSL modem setup which means my
shorewall firewall machine external interface hooks up til my ISP by
directly by DHCP and gets a real internet IP while before with my router
setup .
My question is:
With my Cisco router setup i could from my LAN access my outside IP
