I've recently set up my Mikrotik after running into some issues.
This is what I'm trying to achieve: My Issue
My Endpoints are unable to reach the DHCP server.
If I log into the downstream Cisco switch, I can ping the gateway from the switch. (This gateway is also my DHCP server)
If I set a static IP on the endpoint, I can reach the gateway but not get out to the internet.
If I log into the downstream switch, I'm unable to get out to the internet from the switch, giving me the feeling that I'm running into issues with my Bridge Configuration.
I can ping 8.8.8.8 from the Mikrotik terminal, so I know the Mikrotik has internet access.
Initially, someone suggested it may be a NAT issue. I checked out the NAT documentation https://help.mikrotik.com/docs/display/ ... Masquerade and I feel that my masquerade rule should do the trick.
I'm sure it's something simple that I've overlooked. Any pointers in the right direction would be appreciated.
