2 different IP ranges - how to setup?



  • Hello,

    until now my colleague had setup and maintained a pfSense 2.1.5-RELEASE (amd64), I am very new to that…
    We have WAN on em0 and LAN on em1
    Until now, everything was fine, we had one range of 5 IP
    We bought a new range of 5 IP but of course they are not following the current range and the GW is different...
    I tried millions of things in VIP, NAT, 1:1 rules, nothing is working
    Anyone could help me on that please?

    Thanks a lot

    Alex

    For starters your on a unsupported version..  Why don't you get current, and then we can figure out your issue.

    2.3.1 is the current version.  2.1.5 is few months shy of 2 years old.



  • As JP suggests, backup your config, install the latest release and re-import the settings from the backup, or do an in-place upgrade. I'm guessing here, but you may not have flushed the ARP cache on your firewall after amending the IP/routing (assuming you HAVE amended the IP/routing - you don't actually say so explicitly - in which case the issue is more to do with settings).



  • I prefer not to upgrade now because this firewall is in production and I dont want a system down on the eCommerce website he helps to access.
    Here is what I did

    • added a new gateway on my WAN interface – see screenshot
    • added a NAT to forward one of my new IP xxx.xxx.170.210 to an internal IP (port 3389)

    Is there anything else I should do?

    Where to flush ARP cache on the pfSense?

    thanks a lot

    How did they give you the new range? Did they route it to one of the existing IP addresses?



  • They just gave me the IP range like that:

    Gateway: x.x.170.209
    IP Range: x.x.170.210 - x.x.170.214
    Netmask: 255.255.255.248

    They didnt told me anything
    They are the company that is hosting our server in their datacenter.

    thanks

    Same ethernet interface? Different ethernet interface?



  • SAME

    They should not be giving you two layer 3 networks on one interface. They should be giving you a second interface or they should be routing the new network to your interface address on the existing interface.



  • thanks Derelict
    actually I was focusing on the wrong spot…
    I created VIPs and a second gateway and this was correct.
    But the machine I wanted to reach had its @#$%^ firewall activated...
