I am charge of the switches on a project. I have to configure 2 MDFs which are trunk to each other and 5 IDFs. Another person is in charge of the router and I don't have access to it. The company has bought 6 IP address and the other person is creating a NAT for it to 10.230.100.x.
I ping from IDF3 to the MDF with no issues (both sides I have them set to use a native vlan trunk ). I configure the rest of the computers via switchport access, where the VLAN is 100. When I connect one of the computers to a port the light turns green yet it doesn't connect to the internet. I can't ping from the PC to the Switch or get to the default-gateway. I am thinking something is wrong with the router configuration or possibly trunking is missing between the Router and the Switches (MDF).
PC <--------------X-----------------------> Switch (IDF3) <---------------------------------------------> MDF(1)
Needless to say, I can't ping to the default gateway
