RouterOS General

I configure bridge1 with four ethernet interfaces, these brigde is a
Gateway ( 172.16.1.1 ) for a LAN ( 172.16.0.0) which have acces to Internet throught
a WAN ( ethernet card),

but stations in the LAN not see each other,

Example: 172.16.2.2 can’t ping to 172.16.4.8

I have 2.9.17

Thanks.

If he is, it’s probably a default gateway problem.
