Hi - I need advice how to best connect 10GB switch/router (Mikoritk CRS-305) to my existing LAN setup which is controlled by ISP provided router (Mikrotik RB-750Gr3).
Initially i had 2 machines where i put Mellanox 10GB cards, plugged them into switch and gave them separate LAN segment (10.0.0.0/24) with static IP addresses and it work(s) beatifully between those 2 machines. With samba (both are linux boxes) and i get over 1GBytes per second file copies (from SSD/RAM in one machine to SSD/RAM on the other).
Each of those 2 machines had regular LAN address (10.2.0.0/23) provided via DHCP from 750G router.
Now I want to add 2 more machines that sometimes their only connection is the 10GB and sometimes they have dual ports (connected both to 1Gb LAN as well as to 10Gb segment). Net is - i need to setup routing (i think) from 10Gb switch (CRS-305) which is with it’s Ethernet port anyhow connected to the regular basic unmanaged switch where my RB-750GR3 is having it’s LAN port connected.
Right now with 0 VLANs and 0 routing these 2 segments operate on their own and PCs connected see those 2 as 2 different networks but if i connect only 10Gb device to 10Gb switch - the only way it could go to internet is to route from CRS-305 via Ethernet to basic switch from which it would get to Eth1 of RB-750Gr3 and then to internet.
Rather then me complicating with potential ideas … i did try to use switch as a gateway (Quick Setup mode) … i can ping from the switch everythign on the 1Gb lan side … i have no NAT Rules i guess i do not need them for simple routing. However on the main lan/gateway - i added address/route of the switch and it does not seem to work.
What would be smart advice to keep my backbone at 1GB (cant change cabling and how 3 access points are connected to unmanaged 1GB switch) and just add a segment which is only on 10Gb side and if the client on 10Gb side does not have other LAN or WiFi it should be able to go through CRS-305 to lan to RB-750 (and back)… my guess is i need some smart NAT rule on RB-750 but i have no idea how to do that.
If anyone has added CRS-3xx to their main LAN - i am sure you have probably had a simmilar need and i appreciate any advice/tip etc … !
Thank you !
