We have a Verizon Router and we have configured some port forwarding rules.
For example: port 8443 will go to one of our internal addresses 192.168.1.55. We also have DNS entries for mysite.com to point to the Router Address.
When we are external and visit mysite.com:8443 - everything works as expected. However if we are internal and visit mysite.com:8443 - it spins forever.
I am assuming we need an internal DNS server to resolve? Assuming this is the case and we set up an internal DNS (any info appreciated) - when a request originates inside the network - what is the resolution?
CHECK INTERNAL DNS (would map hostnames to local addresses) AND THEN CHECK EXTERNAL DNS (would map hostnames to router address)?
If anyone could provide any info or confirm what I am saying that would be great.
Router Model: MI424WR-GEN3I Found 'DNS Server' functionality that allows me to enter hostname + ip address combinations but it does not seem this is being used for resolution when i ping from a machine inside the network.
The router connects to a Watchguard XTM515 Firewall which has a DNS Server of 126.96.36.199 setup in its DNS Servers list.
