Sitetosite & remote access

spillek

Hi,
I have a server-pfsense (A) with 2 openvpn server connection:

site-to-site shared key (server)
remote-access
both work, or better, are connect…
and I have a client-pfsense (B) with 1 openvpn client connection:
site-to-site shared key (client)

If I connect with a pc-client to server A by remote-access I can "ping" network lan behind pfsense;
If I try to "ping" by pfsense-client (B) GUI the network lan behind server-pfsense (B), does not work

I do not understand, any ideas ?
thanks in advance, best regards
