In the general sense it’s secure, since the connection is validated by the certs. However, in your particular use case, it does seem that a user could change the Remote ID and access the other VPN subnet. I can’t think of a way offhand to use a cert-based implementation
to avoid that, other than using two VPNs, one for each subnet group (with each VPN having a separate root CA cert so no crossover is possible).</div>

Even if you went to an id/password-based mechanism, you’ll need some way to distinguish the groups. A connection per user would get you there, but that will dramatically increase management complexity, so two VPN servers might be a more management-efficient
approach.</div>

more flexibility to generate this type of VPN cert. Unfortunately, it’s fully built around swanctl/systemd, not the legacy ipsec/ipsec.conf/… configuration. But, if you run into any issues, happy to help you wrangle it into debug mode to use that part of the

I understand the MacOS VPN config correctly (looks a lot like iOS), when certs are installed onto MacOS, you can specify the Remote ID, which is the SAN that matches that of the VPN cert.<br class="">

Someone will likely explain why using certificates sucks, but if you use certificates (one for each client device) you'll have fine-grained user access control (by revoking/deleting certs), and you don't need to list all the enabled certs anywhere in your config

Hi !<br class="">
<br class="">
<br class="">
I installed StrongSwan to allow my users (mainly MacOs X clients) to use the native ikev2 authentication. Everything is working fine.<br class="">
<br class="">
<br class="">
Now I would like to implement something like that :<span class="Apple-converted-space"> </span><a href="https://www.strongswan.org/testing/testresults/ikev2/wildcards/index.html" target="_blank" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">https://www.strongswan.org/testing/testresults/ikev2/wildcards/index.html</a><span class="Apple-converted-space"> </span>;
allowing some clients to access some network and not the others.<br class="">
<br class="">
<br class="">
Unfortunately I didn't see (or understand) the issue on that page (<a href="https://wiki.strongswan.org/projects/strongswan/wiki/AppleIKEv2Profile" target="_blank" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">https://wiki.strongswan.org/projects/strongswan/wiki/AppleIKEv2Profile</a>)
:<br class="">
<br class="">
<br class="">
ASN.1 Distinguished Names can't be used as identities because the client currently sends them as identities of type FQDN.<br class="">
<br class="">
<br class="">
As a result when I put rightid in my configuration it's not working because MacOsX is only sending a fqdn (an email address in my case) and not the Distinguished Name.<br class="">
<br class="">
<br class="">
<br class="">
My question is how can allow (or deny) some network to some user?<br class="">
<br class="">
<br class="">
<br class="">
I have a file that associates email address to "role" but I don't know how to use it. Maybe a plugin?<br class="">

Any ideas/links?<br class="">
