Hi, that’s my first post on forum. I have problem with my network, I’m new in MikroTik gear so it’s not easy to me to understand everything. My network look as shown on attachment.
My problem is that I can’t reach Sony laptop from my PC’s (192.168.1.2 and 1.3). I see Sony laptop from Samsung laptop but that’s becouse they have the same subnet 192.168.80…
I can’t change LAN IP’s to 192.168.80… subnet because that network is bigger than shown on image. How can I connect computers with 192.168.1… subnet with 192.168.80… subnet ? It’s weird because sony laptop has internet connection shared from ADSL modem and it works. What can I check? I can send any information about Mikrotik’s configuration, just write me what to enter in terminal.
Is your Modem aware of the 192.168.80.0/24 network?
You’ll need to add it a route for dst=192.168.80.0/24 gateway=192.168.1.149

Thanks for reply. I add a static route on modem as you say. I add same route on mikrotik with 192.168.80.1 adress. From normal PC I still can’t open any 192.168.80.. adress, can’t ping mikrotik etc. But from samsung laptop connected to mikrotik via wifi I can ping my PC but can’t see shared files in network tab, I can open modem’s page (192.168.1.1). What do you think about this ? Modem is basic sagemcom fast 2704…
Is that 80.1 RB751U still more or less on default config?
i.e. is there masquerading and and firewall rules in place?
If so, disable all and see if it works. Then re-add f/w rules as you need them.
Check if the same counts for 80.2
It is normal that you don’t see other machines in the network tab - that discovery mechanism is link-local.
You need to open it manually (i.e. \192.168.1.2\share) in the windoze exploder when trying to open from the .80 subnet and vice versa.
-Chris
There aren’t firewall rules, just NAT masqerade, I disable them and no change. When I’m trying to open 80 subnet i use adress bar. Maybe I will change configuration to one subnet. Is there any command on miktotik to print all settings at once ?
I don’t think merging two subnets is the solution to the issue - it will definitely work after this but I assume you have chosen to use two subnets for a reason.
If you don’t mind, post the configs of both 751s here and we can look into it to find the problem.
The masquerade rule surely was one part of it.
The command is /export compact - this also answers your second question.
If you want to have the config in a file, append file=config.rsc and you can download that file.

Any ideas about my problem ? 
Remove this completely from 80.1:
/ip firewall nat
add action=masquerade chain=srcnat
add action=masquerade chain=srcnat
add action=masquerade chain=srcnat connection-type="" disabled=yes dst-address=\
192.168.80.0/24 src-address=192.168.1.0/24
/ip route
add distance=1 gateway=192.168.1.1
add distance=1 dst-address=192.168.80.0/24 gateway=192.168.1.149
add distance=1 dst-address=192.168.80.1/32 gateway=192.168.1.1
And make sure that 192.168.1.1 has a static route for the 192.168.80.0/24 network pointing to 192.168.1.149.

I change my modem from Fast to Netgear and add static route and now I can see files from other subnet. Now I remove what you say. BUT… new problem is network transfer that is 200KB/s when I’m trying to send some 80MB video from one subnet to the other. I have read some articles like that https://www.petri.com/forums/forum/client-operating-systems/windows-7/58572-win7-network-access-very-slow, about slow performance of network in windows 7 and I made some changes in windows settings but it’s still very bad. My network runs 100 Mbps full duplex and 200KB/s is way too slow…
