Hi Experts
I have just configured a mikrotik router in bridge mode and trying to apply firewall filter rules but its not working. Details of connectivity and config mentioned below:
Router's Ethernet1 and ethernet 2 interface is running in bridge mode. Both interfaces have public IP. There is another interface ethernet 5 which is LAN interface and there are users connected with this interface to access internet. Ethernet 1 has Public IP address of (203.244.135.171/29) and There is a server connected to ethernet 2 with public IP address (203.244.135.172) which will be accessed by machine located at 83.225.98.42. My task is to allow LAN users to be able to browse internet only and drop everything else .Further server connected to ethernet 2 only accept requests from 83.225.98.42 and drops everything else. filter rule for LAN users is working but it is not working for server. Can anyone help me in resolving this issue.
Thanks & Regards
