Hi all I would like to bind multiple IP, within the same subnet, in a VLAN interface. However, when I did it, the error message "Invalid IP address: A secondary IP address with the same subnet is already assigned for the interface vlan1." showed up. The reason why I want to bind multiple IP within the same subnet to a VLAN interface is to configured multiple 1-to-1 NAT. e.g. 192.168.1.10 is NAT to 10.100.10.5 and 192.168.1.11 is NAT to 10.100.10.6.

Hi Adrian Sorry for late reply. I have tested RFS with 4.3.x. I have two findings: 1. In CLI, the secondary IP can be added within the same subnet of primary IP. 2. In GUI, the secondary IP still cannot be added with an IP lay in the same subnet as primary. Please check the attached image. In anyway, the WiNG 4.3.x can solve my issue, even it must work with CLI. However, I can't find the latest implementation for WS5100 has this feature. That is still a problem to me that I need upgrade the old WS5100. Regards Antony
Hi Alex
Thx. I have already read the doc before. I can do the static NAT as described inside it.
What I am not able to do is binding two IPs, within the same subnet, onto the same vlan.
The static NAT in the example is performaning the translation on the ip of VLAN 4094 into the internal ip. If I want to translate another IP, say 76.1.160.2, I am unable to reach the translated machine by 76.1.160.2 as the network cannot resolve 76.1.160.2.
Therefore, I would like to bind two IPs on the VLAN4094 as follow:
interface vlan4096 description INTERNET ip address 76.7.160.1/24 ip address 76.7.160.2/24 secondary ip address 76.7.160.3/24 secondary ip nat outside !
Where the 76.7.160.2 & 76.7.16.3 will be translated into two different machines inside the private newtork.
interface vlan5 ip address 192.168.5.71/24 ip address 192.168.5.72/24 secondary RFS7000#sh int vlan 5 Interface vlan5 is UP Hardware-type: VLAN, Mode: Layer 3, Address: 00-15-70-38-02-de Index: 6, Metric: 1, MTU: 1500, Status-flags: IP-Address: 192.168.5.71/24, broadcast 192.168.5.255, primary IP-Address: 192.168.5.72/24, broadcast 192.168.5.255, secondary input packets 0, bytes 0, dropped 0, multicast packets 0 input errors 0, length 0, overrun 0, CRC 0, frame 0, fifo 0, missed 0 output packets 33, bytes 924, dropped 0 output errors 0, aborted 0, carrier 0, fifo 0, heartbeat 0, window 0 collisions 0 Tested with Wing 4.3. If I understood your question right, I am not sure about that...
Hi Adrian Thansk for advise. You are right. These is what I was looking for, I am using WS5100 with firmware 3.3.3. When I added the second interface with the same subnet in the VLAN, I got error. You mentioned in WiNG 4.3, it should be no problem. I think that I would try the newest firmware or try in a RFS switch to see whether it is the limitation of my running version. Regards Antony
Antony See the section Static NAT on the attached document to configure what you are trying to achieve. More of these can be found at: http://motopedia.mot.com/wiki/EWLAN-HOW-TOs Hope this helps.
