Several /30 networks to pfsense



  • Hi,

    i have a pfsense running in firewall mode to protect a /27 Subnet.

    Now, i got another /27 subnet assigned, which will be devided into 8 /30 networks.

    How do i need to configure the pfsense to add this /30 networks?

    Whats the best way to get it running? /30 includes 2 Hosts, one is the pfsense and the second is a server, that for each subnet.



  • Create vlans on switch and on pfsense



  • Why VLAN? I need this /30 subnet.



  • If you need multiple /30 to isolate hosts, the best way is to apply one ip for each /30 network on pfsense and other on host.

    Vlan will isolate on network to other.

    These is Also a quite odd setup That you assign /32 ips on hosts and define gateway based on interface/out of subnet ip.



  • I've done that.

    one ip to the pfsense, another to the host.

    added firewall rule for ICMP, now host can ping pfsense. But pfsense is not routing the traffic from the host to the WAN, why?



  • How many /30 ips did you assigned to pfsense?

    Check firewall - nat - outbound



  • currently only one to test it.

    Firewall is LAN -> WAN "Default allow LAN to any rule "

    Outbound NAT is "Manual Outbound NAT rule generation" with no entry.



  • @repa:

    currently only one to test it.

    Firewall is LAN -> WAN "Default allow LAN to any rule "

    Outbound NAT is "Manual Outbound NAT rule generation" with no entry.

    When using manual outbound, you need to specify outbound nat.

    Change it to manual to test and then Back to manual.
