I have two router 750up connected by ether5 with a third common subnet The router have with 2 differents subnet but no connection between host??? I want my computer to access my camera.
Here’s my setup:
MKT#1

[admin@TX] > ip address print

ADDRESS NETWORK INTERFACE

0 ;;; default configuration
192.168.88.1/24 192.168.88.0 ether2-master-local
1 192.168.11.1/24 192.168.11.0 ether5-slave-local

[admin@TX] > ip route print

DST-ADDRESS PREF-SRC GATEWAY DISTANCE

0 ADC 192.168.11.0/24 192.168.11.1 ether5-slave-local 0
1 ADC 192.168.88.0/24 192.168.88.1 ether2-master-l… 0
2 A S 192.168.90.0/24 192.168.11.2 1

Host is a camera who’s 192.168.88.100


MKT #2

[admin@RX] > ip address print

ADDRESS NETWORK INTERFACE

0 ;;; default configuration
192.168.90.1/24 192.168.90.0 ether2-master-local
1 192.168.11.2/24 192.168.11.0 ether5-slave-local

[admin@RX] > ip route print

DST-ADDRESS PREF-SRC GATEWAY DISTANCE

0 ADC 192.168.11.0/24 192.168.11.2 ether5-slave-local 0
1 A S 192.168.88.0/24 192.168.11.1 1
2 ADC 192.168.90.0/24 192.168.90.1 ether2-master-l… 0

Host is a PC who’s 192.168.90.254
I Have 2 different subnet wich must stay in these form, no possibility to put them on the same subnet or network. The third is to able communicate in between. The ether 5 as no masterport. From any router i can ping the gateway and the host of the other but i cant communicate from host to host, PC 192.168.90.254 to the camera 192.168.88.100??? No firewall rule not NAT roules. Any help would be really appreciated.

Is there a default gateway set at the camera?

I think that the default gateway in the routerboard is created with the default configuration it’s suppose to be the address of the router?:
0 ;;; default configuration
192.168.88.1/24 192.168.88.0 ether2-master-local

But maybe there’s a place were i have to indicate the routerboard that the gateway is 192.168.88.1??? I’m don’t know?

Or you mean in the camera setup??? My camera is dhcp client, but i can try to static it with all the current ip plus the gateway…

can you please post a full export of both routers?

Ok i’ve found the error but not the solution, thanks Pukkitta with your request i’ve ask myself if there was anything else in the setup that was creating a bug, here’s the answer:

I’m using a public network OR a Wireless local bridge depending the environement to transmit image from camera to a computer, the DVR install in the computer need to see the same address when connecting, i cannot connect once with a public address than later connect to local address cause it recongnize the mac address of the camera and say ‘‘already added’’ . And deleting and creating a new setup every time on the DVR is not practical, i’m not behind the screen of DVR.

So to always be in the same address have created a VPN in between routers and to do so made a policies that say ‘’ if connect from 192.168.90.0/24 to 192.168.88.0/24 than encrypt’’ with all the peers and everthing. What i didn’t know is even if the peer was unavailable (disconnected wan network) this policies took place. When i’ve disable this policie everthing worked perfectly.

So now i’m looking for solution, i’m a beginner so a was thinking maybe something esle : ipip tunnel or gre tunnel but i don’t know if it’s possible to keep being in the local address from one point to the other?

Thanks!

I can’t see the whole picture, a detailed diagram would be helpful to suggest alternate solutions…

Does the DVR software really care about the MAC address of the camera, or is the MAC address of the camera also the serial number of the camera [very common with other networked stuff, at least], which is sent to the DVR somehow in an L3 packet?
