Im running an exchange server beings my 2800 router and its all working well i have setup NAT and OWA is working well when external and on the internet but when the phones are on the internal wireless OWA isnt working and if u telnet the external ip on that forwarded port it dosnt forward i belive this is the fact the port forward rule "ip nat inside source static tcp 10.0.100.7 443 interface Dialer0 443" is for the dialer interface only and as im internal nothing but im show show how to forward any request on that port.. ill incude the config  below

What is the subnet for the wireless users?

Why are you configuring the following two differently?

ip nat inside source static tcp 10.0.100.7 25 interface Dialer0 25

ip nat inside source static tcp 10.0.100.7 443 x.x.x.x 443 extendable

Hi Farrukh

Thanks for the responce

the wireless phones are also on the 10.1.100. 0/24 subnet

i used the different way just testing they where all the dialer 0 way before the other one was just me playing around trying to get this working...

thanks again

Dave
