SrcNat Help

RouterOS General
1

I have a public ip subnet lets say 8.8.8.1-8.8.8.20 these are assigned to a mikrotik. The mikrotik then has a private ip range of 192.168.1.xx. The publics are dstnat to the privates with the same ending number.

So. 8.8.8.1 is nated to 192.168.1.1 and so forth
we also have a srcnat for 192.168.1.1 to netmap to 8.8.8.1

from the server 192.168.1.1 that is netmap out 8.8.8.1 they can not access anything by using the public ip of a different server on the network like 8.8.8.8, however they can if they use 192.168.1.8 which is netpmaed to the 8.8.8.8 because its just local addresses.

These rules were working with 5.14 but are not working with 6.3 firmware.

I know 8.8.8.8 is a subnet held by google. I changed the subnet for privacy.

Any help would be awesome.

You should look for hairpin nat

I did a srcnat with src address 192.168.1.0/24 to dst address 192.168.1.0/24 and masquerade and it still does not seem to be working. I tried putting it at the top of the list and it still doesn’t work.
