Phase 2 question

  • Hi,

    I'm new to pfsense and I'm doing an ipsec site-to-site vpn. latest version

    site 1 :

    subnets A,B,C

    site 2 :
    subnets D,E

    do I have to create  a phase 2 for every subnets (kind of a full mesh) ?

    example :

    site 1
    A to D
    A to E
    B to D
    B to E
    C to D
    C to E

    site 2
    D to A
    D to B
    D to C
    E to A
    E to B
    E to C

    I hope not…that's a lot of configuration when you have a lot of subnets

    BTW, I can't do CIDR in that case...

    thanks !

  • This should work nicely with Alias.

    Just go to Firewall->Alias and add the subnets to an alias, and use that in IPSEC rules.

    I have not tried that there yet, but use it at other places for similar rules ("complicated" networks).

  • yeah looks like a very good idea but it seems we can't use alias in ipsec configuration

    :'( :'( :'(

  • no one has an idea on how to do it ?

    Aliases won't work there. You will either have to make each combination of P2 or, if the subnets are next to each other and line up nicely, summarize them with a larger mask.

    If you can provide some more detail about the networks (even just the last 2-3 octets), perhaps we can offer some suggestions about how to craft the P2s
