I would like to open all ports on the MikroTik towards a device. I created a NAT rule with dstnat towards the IP of the device, using the TCP protocol and a port range of 1-6500. As soon as I activate this rule, the device stops browsing. It doesn’t load pages. What am I doing wrong
Without seeing the config I can’t tell nothing, so:
export file=anynameyouwish (minus sensitive info)
It sounds like you almost dont need a router if opening all ports up.
Typically I advise that its a foolish thing to do… especially if your router is public IP facing.
Except of strangeness of your action, what you’re doing wrong is probably not specifying restrictions on dst-nat rule, so ports 443 and 80 for outbound also match it and are being forwarded.
Found the solution, I had to set the in interface. Now everything is working fine.
By the way I’m opening all ports because my mikrotik is connected to another router where I have a firewall, so I don’t need to block any port on the mikrotik, I already handle it in my other router.
That’s weird anyway. Either setup proper routing or connect in bridge mode then
