*Urgent* Global Protect Crypto

I have one more query, If I change week encryption to strong encryption in tunnel traffics like Global Protect, IP sec tunnels, will it get affect the clients ??

Of course We have to check the peer side before we change the encryption methods & algorithms for IPsec tunnel but what about global protect ??

If we change the GlobalProtect IPSec Crypto's encryption method, will this change affect the client connection ?

Will all the GP version's supports aes-128-gcm & aes-256-gcm on client side ?
Will they able to connect with LDAP ?

Thanks & Regards,

Hi @sahithyan.subbu ,


The operating system of the endpoint determines what cipher suites the GlobalProtect app includes in its Client Hello message.

As long as the GlobalProtect app includes the cipher suite that the gateway prefers to use, the gateway will select that cipher suite for the SSL session.
