Firewall rule filtered on vpn connected clients

Hi All,

I would like to forward only certain ports for VPN connected clients.
But in the firewall rules i do not seen any differences in the logging for a client connected via VPN of directly connected
Which items should be different so i can distinct a VPN connected client from a normal client?

It always seems to come from my pppoe interface from the same source ip, is there a way to change the source?

I have created a L2TP Server Binding for my l2tp connection, and it comes online perfectly, but the source still seems to be pppoe instead of l2tp-user
how can i configure the router so in the firewall rules the source is the local ip i have defined in the l2tp configuration and is as shown in the L2TP Server Binding?

In the PPP profile, add the names of input and output filters you want to use. Then in Firewall/filter, add rules to these chains.
