I have a small business network running one server (SBS 2003) with about 7 workstations. The server has been configured to forward a copy of all my mail (for my user only) to my home email address (a gmail account), this has worked fine for years.
Recently our TP-Link router began to misbehave (had to restart it every day to restore internet connection), so I replaced it with a new TP-Link Archer C-9. I copied all the settings from the old router into a Word doc, and configured the new one with all (I think) the same settings. (Tried exporting settings from old one & importing into new router but new one didn't like the exported file.)
Everything is working fine EXCEPT two things:
1) My mail is no longer forwarding to my home address. I don't get any error messages or anything, just no mail at home. Emails that are MANUALLY sent out to my home address DO go through, just the automatic forwarding has stopped working.
2) We use a little instant messenger program called Big Ant, and now my home machine cannot connect to the Big Ant server - which is my workstation at the office. All other machines inside the network can connect to it fine, just not my home machine which of course is outside the network (this was working fine before the router change).
Nothing on the server has changed, nothing on my workstation has changed - only change is the new router.
Appears to me that the new router is blocking these communications for some reason.
Any ideas are much appreciated!
