Configuration about multiple same LAN IP

Dear support team,
We have one of our configuration as below.

We need a configuration with using telnet with SNMP command by WAN(port1) to 4 of LAN(port 2 to port 5)which all the LAN port with same ip address.
SNMP command as example: snmpset -v 2c -c public 192.168.100.1 .1.3.6.1.4.1.4413.2.99.1.1.1.2.1.2.1 s password

As we configure with NAT rule, but the traffic can’t pass through,so is possible that you can suggest if there’s any configuration to cover this test method?

If you want to access multiple devices with same address (which is not exactly correct, but I’m sure you know that and have your reasons to do so), you can find some inspiration in this thread:

Hi,
As we configure in that topic, the NAT rule is not working well…so it’s possible that you can help us to check the configuration?

Our configuration as attachment,we set ether1 NAT to ether 4&5, and first we set NAT with ip address is working but is not allow to receive the traffic in two same physical interface, only allows once.
test1.rar (6.22 KB)
BTW,is it possible that I can configure the NAT rule just by physical interface for source and destination port without configure the ip address and port number?

Thanks a lot for your help!

You posted backup, that’s no good. Use export:

/export hide-sensitive file=myconfig

and then paste content of resulting myconfig.rsc here in code tags. You can also expand the question a little, I’m not exactly sure what you mean.

Btw, there’s also extended variant of that config in this thread which allows connections from those same-address devices to outside. I’m not sure if you needed, so for the record.

Dear Sob,
Thanks a lot for your big help.
Recently we have more clarification about our architecture.
After we configured with the step you mentioned at your reply post, is very similar and after we do some config is working well.


Btw, few question about about hardware model.
The previous we purchase is RB750Gr3 HEX, now we need addtional one for 10 ports.

We found two of model with RB2011iL-IN and RB2011iL-RM, is there any hardware difference between these two?

Thanks!

-IN is a desktop version and -RM is rack-mount version of otherwise identical device.
