RED's cant connect to certain site

Hello,

I have a internal ip address of 192.168.3.245, its my vcenter. Is resolves fine to vcenter.xxxxxx.local However any office on a red device can ping the ip and vcenter, but when they try to go to the vcenter.xxxx.local or the ip address its giving them an error of host not found. Anyone at the home office not on a red can access it fine. Any ideas'

Thanks.

Yes ICMP is handled by the UTM. Your other traffic needs routing and firewall rules.

Hello,

I have red's configured with routing and firewall rules. I can get to other ip address via a web browser, just not the vcenter.

How is DNS resolved at the REDs? I think the REDs are not bridged, right?

Correct, they are not bridged. I think it has to do with DNS, as when I go to the ip address it pulls up but when you go to log in, it takes you to vcenter.alliance321.local which does resolve, but I think the red can not see the FQDN of vcenter.alliance321.local.

If I add, vcenter.alliance321.local to Add DNS Request Route, then use target as domain controller which is running my dns role would that fix the issue?

Todd, please compare your setup to DNS best practice.

Sorry for late answer. Like Bob wrote please follow best practice. But I think yes. The devices behind the RED should resolve the name for the vcenter. DNS is essential for vcenter. What would be the best approach depends on your DNS setup, but try a req route.
