On layer 3 windows file sharing used port tcp 445 i accept this port file one rule tcp src one rule dst port
But until \IP address no access to file server
Please help me
I use router OS version 6.40.8 (Bugfix only)
It is difficult to understand what you are trying to accomplish. I assume you are trying to open TCP/445 from the outside through the firewall. If so then it is a 2 step process:
Step one, you need to define the dstnat rule:
/ip firewall nat
add action=dst-nat chain=dstnat dst-address=publicIP dst-port=445
protocol=tcp to-addresses=Internal IP
Step two: Add a firewall rule to accept traffic:
/ip firewall filter
add action=accept chain=forward dst-address=
internalIP dst-port=445 protocol=tcp
…step three, move the rule added in Step 2 to a proper position in the list of rules, because rule order matters.
Traffic On my router is Forward To other hop (My router Forwarded Traffic To other Routers )
Donnot terminate Samba traffic on my royter That i write DST nat or other Rule
My question is My router donnot Forward File sharing traffic To other Hops
Are you sure it is your router, not maybe firewall on server doing fie sharing blocking traffic coming from outside its local subnet?
If you have different subnets for your computers, browsing via SMB is not possible across those subnets, because broadcasts packets are not forwarded.
To achieve this, you need a WINS server and register all clients to it.
No need for the forward accept rule.
