Sky / Sagem / Home Exchange / Farting about

[Fluffy]

Ok, after spending 4 hours faffing with this im at the end of my rope, help !

A bit of background

I have a Home Active Directory domain and exchange ***.co.uk (taken out domain name, PM me if you need it for support!)
I Use SKY broadband (now have a SAGEM Router because my netgear died)
I use DYNDNS to redirect

ok, so here is the problem ..

After my netgear died I was sent a new router. Works fine for internet and all that and I have the following port forward rules on my router

Redirect Incoming
Port 25 to my server Internal 192.168.0.10 (SMTP)
Port 80 to my server Internal 192.168.0.10 (HTTP for OWA)
Port 443 to my server Internal 192.168.0.10 (HTTPS for OWA)
Port 3389 to my server Internal 192.168.0.10 (RDP)

keeping up so far ? Good, this is where it gets complicated ... so when Im at work I can goto

https://***.dyndns.org/exchange
or event
http://***.dyndns.org/exchange
and it works fine ..

but if I am on my home LAN (either wired or wireless) and goto

http://***.dyndns.org/exchange ... i get redirected to my ROUTER login page ... wtf ?

and if I goto

https://***.dyndns.org/exchange (again while internal) I just get timed out ...

it obvious to me whats wrong ... its f*cked !

you cannot use the dhcp on the router unless it allows you to specify the DNS rules for your network, as you need to use another DNS server as your primary.

Set up DNS on your internal server and set up the primary DNS in DHCP to point to it

THEN set up a rule in your DNS server for your dyndns address to point to the INTERNAL IP

so when you are at home the dyndns record points to the internal IP and externally it will point to the external IP

Nice one bruv .. managed to sort it .. dont know why SAGEM router wouldnt re-rout the dyndns internally without that setting, how odd !

Working ok now !
