1:1 NAT working for one but not for another



  • We have two websites set-up on our network:

    • Local website set-up on 209.59.59.194 goes to 192.168.1.4

    • Local website set-up on 209.59.59.196 goes to 192.168.3.4

    209.59.59.194 routes correctly while 209.59.59.195 does not route anywhere despite being the same set-up, but different network. I'm not quite sure what else could be checked here. I've attached our firewall rules, as you can see nothing is special.

    Note that: 209.59.59.194 is our main IP for accessing the web however our ISP has given us a bulk of addresses so 209.59.59.195 is ours also and is not used.  Also, both websites work internally using the internal IP addresses.

    WAN = LIME
    LAN = WIRELESS (192.168.1.1) and LAN (192.168.3.1)

    NAT:
    IP's are changed for security purposes

  • You wrote .195 but have 1:1 on .196, maybe typo there? Otherwise, you're likely missing a virtual IP on the public IP that doesn't work.

    That was a typo, I went ahead and corrected it.

    Well why do you think that 209.59.59.194 worked? After adding the 209.59.59.196 virtual IP, still no luck.

    Virtual IP's:



  • .194 works because it's your WAN IP, hence already answering ARP. Packet capture on WAN, filter on the IP that's not working, what's that look like?
