PFSense as second gateway on LAN-Cannot access WAN IP



  • Hello,

    The title is not very informational, but here is the thing:

    I am experimenting PF 2.0 in an Alix board, before put it into production. I have put Alix into the company's network, and I use it as gateway in specific machines.

    I have set a WAN as PPPoE and create NAT rules, which they work.

    The company is not using PFSense yet as gateway, but another ADSL line.

    When I am inside the company's network, I cannot access the WAN IP of the WAN that PFsense has (eg. a web server). When I am outside, I can use this WAN fine.

    I am not having PFSense as gateway, so NAT reflection is not the issue.

    Sorry if the info is not clear enough. Additional info is available.

    Best regards

    Kostas

  • Are you trying to send them to the internal address or the out the existing firewall to the internet and then in through WAN on pfSense into the Exchange server?



  • @podilarius:

    Are you trying to send them to the internal address

    No. If i send them to the internal address it works.

    @podilarius:

    or the out the existing firewall to the internet and then in through WAN on pfSense into the Exchange server?

    Yes, exactly.

  • does the exchange server have the pfSense gateway as it default router?



  • or do you have static route on the old LB to the mail server?



  • @podilarius:

    does the exchange server have the pfSense gateway as it default router?

    Yes, else there was no NATing.

    No static route.

  • Then the computer that are using the other gateway should have access through unless you have created some strange firewall rule in pfSense that is blocking the IP from ISP1 and 2. It should treat those as external IPs. CAn you screen shot your rules and your NAT for this?
