6to4 tunnels working for me again (SixXS), finally able to upgrade from 6.19. :) I spoke too soon. The tunnel itself remains up, but assigned address becomes invalid after a while.

6to4 tunnels working for me again (SixXS), finally able to upgrade from 6.19.

IPv6 is broken in this release. Configured address showed up as "invalid" in /ipv6 address. Downgraded to 6.19 again, everything works fine.

I think I figured it out. This seems to be working: /ip firewall mangle add action=mark-connection chain=prerouting dst-port=2222 new-connection-mark=ssh-redirect protocol=tcp /ip firewall filter add chain=input connection-mark=ssh-redirect dst-port=22 protocol=tcp add chain=input connection-state=e...

I see, any idea on how to tag the redirected packets?

I want it accessible on port 22 from internal networks.

I'm trying to make SSH available on a different port on external networks. My current NAT and filter rules: /ip firewall nat add action=masquerade chain=srcnat comment="default configuration" out-interface=ether1-gateway add action=redirect chain=dstnat dst-port=2222 protocol=tcp to-ports=...

I didn't get as far as the NAT rules. I must use DHCP to assign the two IP addresses to each port, and adding a DHCP client to port 5 causes routing conflicts as both IPs are in the same subnet. The default gateway becomes reachable through both ports. The same thing happened even when add-default-r...

I tried making port 1 a part of bridge1 (along with port 4 and 5), but the traffic between bridge1 and bridge-local (my LAN) then gets limited by the CPU to around 20MB/s.

I'll look into hairpin NAT. Thanks.

Hello, I'm trying to pass traffic between two WAN interfaces using RB751G-2HnD running RouterOS 5.20. This is my current configuration: - Port 1 and 5 on my Mikrotik are each connected to bridged ports on my ISPs router. A public routable IP address is assigned to port 1 via DHCP. - Port 2 is my LAN...
