Unable to connect to rogue dhcp server inside network

RouterOS General
1

Hello.
I.eg. there is some rogue dhcp router in my network, normally on my linux machine I use tunel to connect to it and disable dhcp server remotly.
I tried to do this on rb750 with dst-nat and it doest work. For example rogue dhcp server has ip 192.168.69.1 so my config is:

chain=dstnat action=dst-nat to-addresses=192.168.69.1 to-ports=80 protocol=tcp in-interface=ether1-WAN dst-port=8000

/ip firewall nat print stats gives"

CHAIN ACTION BYTES PACKETS

2 dstnat dst-nat 5 856 122

so some packets are flowing but it doesnt work at all.

But if I make some other redirect i.eg. to my machine in my network it works normally so my config is ok.
Ofcourse host is reachable:
/ping 192.168.69.1
HOST SIZE TTL TIME STATUS
192.168.69.1 56 64 10ms
192.168.69.1 56 64 0ms
sent=2 received=2 packet-loss=0% min-rtt=0ms avg-rtt=5ms max-rtt=10ms

Any ideas?
Thanks in advance.
ROS is 5.25

Chances are your server’s default gateway is not set properly, so you cannot get to it. Do a src-nat rule with an out interface of the LAN and that should allow you access.

I added:

3 chain=srcnat action=masquerade dst-address=192.168.69.1 out-interface=ether2-master-local

and it works, thanks.
