SBS is its own beast.

Everything ported great and internal clients have no problems, using
http://www.mydomain.com or https://myip. however when i am outside
the office I cannot use http or www, only https. I need to change
either the port on the "Welcome to SBS server" so that http works.

You really do not want to open port 80. It's quite dangerous enough to open
up 443 for SSL secured access to your SBS server and LAN. Perhaps your
public DNS host can create some sort of aliasing/redirect for you - so you
can just enter remote.mycompany.com and have it redirect to
https://my.domain.com/remote . Either that, or you could simply get used to
the minor inconvenience of typing in https://my.domain.com/remote.


thanks, is their a way to change the port to 81 or something?


When i do a port scan from outside the only open ports i have are
tcp/25 and tcp/3389.

You need 4125 also, if you're going to use RWW. And you don't absolutely
need 3389 - you can do server mgmt via RWW (and subsequent RD to the
server).

how and where do i do this

If I run netstat - a I do not see port 80? I
have run CEICW numerous times and have enabled these ports.

You'd need to have it open / forwarded in your router/firewall.... I hope
you have one, and aren't just using 2 NICs and the built-in stuff!

due to budget constraints i am using the min requirements, 2 nics no external
firewall, using sbs2003 software basic firewall

If I
check my network connections for HTTP on /ROUTING AND REMOTE/IP
[quoted text clipped - 8 lines]
I am not sure if my ISP blocks port 80, ( two much trouble to find
out - they are not very co-operative)

You might consider getting a business-class account from a better ISP, then.
If your ISP blocks port 80 inbound it tells you that they don't want their
customers running webservers, and you may be in violation of your agreement
with them. That said, if you don't have any of your own stuff blocking port
80, and you can't get in, then it's probably them.

how do i check if it is not an internal block? ( is there some software?)

How cannot i redirect my traffic so that HTTP works, i need this for
exchange updates to a mobile phone ( ie exchange logs in via the
ipadress)
thanks

Ah, that's the detail I was missing above. What kind of mobile phone is
this, and doesn't it support SSL ? I bet there's a better way to do this,
but we'd need more info from you...

the phones are tmobile mda's and verizon xv6700's. when i sync inside the
lan it works great( connected to a pc) outside it does not connect, just
shows "waiting for network". i know that if http works i can setup the phone
to loginto the server via the ip address, I have run vpn wizard etc nothing
works, the whole issue above is so that employess calendars and emails are
update externaly and visa versa. any help would be appreciated. i have reset
the phones, reinstalled activesync, but get still get server problems. based
on past experiences and forums i now that most people recommend diasabling
SSL as this solves a few problems for companies with budget constraints, ie:
our certificate is created through CEICW not bought. i remember that there is
a workaround by changing port 80 to 81 which will allow http access

thanks
