Why email is not being picked up by SBS 2003 since new router install
Posted on 2013-05-22
I've been asked by our ISP to install a new or known working router to our connection as it's been dropping out and they want to rule out any possible faults with the existing router.
So I have everything setup and we have connection to the internet which does seem more stable, albeit a little slower.
The replacement router (the only spare I have) does not allow for changing of LAN I.P either to the local address of the router or across the network.
Luckily it's on the same subnet as the existing (192.168.1.1) router, but has the default of 192.168.1.254, which can't be amended - I've changed the SBS LAN connection setting to point the gateway to this address and as mentioned above, we have a working internet connection across the local network.
My issue is that although users/clients can send email out, they cannot receive email since the swap. Is there something in Exchange that might need amending to the new router local I.P? My only other thinking is some sort of port forwarding needs setting up, but I don't think this router can do that.
