I hope this is an appropriate question for here. I'm a software guy, I usually do "ok" figuring stuff out, but I can't get this one. I know it's easy, too.. I just can't get it, and I need help.
Problem arose after switching to Comcast Business.
- Comcast Business router, Cisco DPC3941B
- Static IP, DMZ to server
- SmarterMail Email Server
Email is not sent from, nor delivered to phones on local network wifi. If I turn wifi off on the device, and "resend" over 4g, success. If I am connected to any remove wifi network, success. Issue is only over local network.
I have no idea if this is a setting in SmarterMail, in my router, or what to do. I'm hoping that you guys can have mercy and give me a hand.
Please let me know what information you need if you are willing to assist. I don't even know what router or server settings to give you.
Thanks in advance guys, R/
NAT Configuration 1 [static IP address] 10.1.10.99 [Enabled]
No Static Routing
Dynamic DNS Disabled
Let me know if this is enough or if anything else is needed.
