Hello, I am looking for some help with my Vlan communication on one of my Mikrotik networks.
I have an RB1100AHX2. It is the core router for two other Mikrotiks:
ETH-1 is my internet gateway on a public /30
ETH-2 has two vlans on it 501, 502 which connect to a trunk port on a Cisco switch and communicate with two more mikrotik routers each talking to this one using their respective vlans 501, and 502 each of these mikrotiks are connected to trunk ports of Cisco switched on the other sides of their respective wireless point to point transparent bridges.
Each of the mikrotiks on the other end or their p2p have access points I want to monitor with snmp udp port 161.
On each of the other Mikrotiks the vlan (501 or 502 respectively) is on their gateway port then there is a device bridge that has a small subnet with .1 assigned to the bridge and the rest of the IPs in the subnet go to access points with .1 as their gateway. These access points are plugged into the other ports on the router that are members of this bridge.
Also on each of these Mikrotiks is a PPPOE server assigned to each routers device bridge for customers that get a /24 of their own assigned to them and routed out to the internet.
Everything from each of these routers leaves through its vlan (501 or 502 respectively)
ETH-3, -4, -5 ports on the RB1100 belong to a bridge that has xxx.xxx.xxx.249/29 assigned to it and plugged into one of these ETH ports is my linux server with xxx.xxx.xxx.250/29 assigned to its interface with xxx.xxx.xxx.249/29 as it’s gateway. I have Cacti running on this server.
I can ping everything form anywhere and everything works fine with internet traffic.
I need this server to be able to get the snmp packets from the access points on the other end of vlans 501 and 502 and I’m not sure how I can do this.
I should add two that all the subnets on the two other Mikrotiks on vlan 501 and 502 are private IP subnets with NAT running for them on the RB1100 core router for internet traffic. But this should cause any problems at all because all these routers are directly connected via the vlans so anything on the subnets that they all three use do not leave the RB1100 core router so the intercommunication between all three shouldn’t be hitting the NAT at all.
I’ve tried to think it out but admittedly Vlans are still a bit confusing for me.
I would be grateful for any help any of you could give me with this.
