Did you have another router plugged to the fibre connection before? Was it working? What model?


Why did you buy this Cisco? What were you trying to achieve/solve?

If you don't know what you're doing with a Cisco router and know how to configure IOS then perhaps a consumer grade router would be more appopriate.


Or specifically this one:


With selecting UFB on VLAN 10 would probably give you config close enough to what you need.

The cisco 2901 is already obsolete, it can only push 150mbps before NAT and any ACLs

Add IPSEC, necessary ACLs to secure things and you are looking at performance of only 80mbps so even a 100/20 connection will be hindered by this router
