hi all
my network setup is basic using the default config
wan is on ether1 via a fibre connection using pppoe dynamic ip address
lan is on eth2 to a unmanaged switch
doesn’t matter what i do cannot get it to connect from other wan connections
its a team speak server so udp port 9987
local lan ip to
its so annoying because normally i can figure this stuff out
any idea guys
i did a shields up says everything is closed
/ip firewall nat

Feel the difference?
Your internet connection is “pppoe-out1”. Use this name for all external rules.
still no luck 
rebooted as well current config
so ive changed nat to the pppoe-out1
not to sure what to put in filters i remved the ones i had mad thinking they could have been the issue.. so now filters i think is in its default state
not sure what to do next
EDIT: got it going 
had to move rule up the list and it worked

I’m having the same issue, It’s almost embarrassing to admit.
Ever since I upgraded my mikrotiks to v6.20 simple port forwarding doesn’t work. I tried sniffing, inbound and outbound. traffic comes and goes, I can not capture packets on the WAN so I cant tell you if NAT is actually translating the source address.
However I have had several other mikrotik certified trainers look at this. Everyone agrees that the config is setup properly.
here is the config, so simple it’s embarrassing:
/ip firewall nat
add action=masquerade chain=srcnat out-interface=ether1-gateway
add action=dst-nat chain=dstnat connection-type=“” dst-port=80 protocol=tcp to-addresses=192.168.1.15 to-ports=80
and yes, the default gateway on the internal host is correct…
if anyone knows what to do, let me know,
I’m going to downgrade those mikrotiks which have v6.20 on them.
pennytone,
Try to change a port. I think that 80 is busy by RB (web interface).
Or change www-port in “Winbox-IP-Services”.
