When you're accessing an IP address on another subnet and the gateway isn't 
properly set, you need to use SRCNAT and DSTNAT. 


Someone earlier said to set the 169.254.x.x IP on the MT and to then telnet 
from the MT. That's the least complicated way.

For some reason, that's not working either. 

Got the PTP650 on ether9 on the MT. Ether9 gets IP 169.254.1.3/16. 

I created a reachable address on the local interface (192.168.222.199). 

Then I added the dst-nat: 

/ip firewall nat add chain=dstnat action=dst-nat dst-address=192.168.222.199 
to-address=169.254.1.1 

I ping the 192.168.222.199 address from a PC on the local network, but nothing 
happens. Torching the port on the MT shows nothing happening on any IP on that 
port (except discovery).

OMG Bill. You *have* to learn how to DST-NAT. Great for programming Canopy 
radios and best get-me-out-of-this-jam rescue trick EVVVER. Access any device 
on any MT router anywhere—even when not routable. No VPN required. No need for 
Telnet tunneling. 

First put the SM on a MT interface and assign 169.254.1.2/16 

Two variants to pick from: 

Add a new [reachable_address] on the MT that you don't need for anything else 
then: 
/ip fire nat add chain=dstnat action=dst-nat dst-address=[reachable_address] 
to-address=169.254.1.1 
Then http://[reachable_address ] to get to the SM 

Or use an existing MT address and map from an unused port like this: 
/ip fire nat add chain=dstnat action=dst-nat dst-address=[reachable_address] 
dst-port=8169 to-address=169.254.1.1 to-port=80 
Then http://[reachable_address]:8169 to get to the SM
