AltocumulusHi all,
Could you help me how to disable only TLS v1 & TLS v1.1 on specific virtual server and no to entire ssl profile.
Thank you in advance,
try this irule:
when CLIENT_ACCEPTED {
SSL::profile vip_ssl_no_TLSv1
}
where vip_ssl_no_TLSv1 is another SSL profile where you disable whatever you want.
I tested with this cipher string : DEFAULT:!TLSv1:!TLSv1_1
MVPUsually, you have an SSL client profile per virtual server, right? I don't see why you want to do it in an irule.
You can try to reject the connection if it has a TLS version, but I don't know if you can change the TLS version:
when CLIENTSSL_CLIENTHELLO {
if {([SSL::cipher version] equals "TLSv1.1") || ([SSL::cipher version] equals "TLSv1")} {
log local0. "DETECTED-TLSv1-CONNECTION - LOG_SSL_LEVEL - REJECT Client: [IP::client_addr] [SSL::cipher version] - [SSL::cipher name] - [SSL::cipher bits] - For the VIP - [virtual name]"
reject }
else
{
log local0. "DETECTED-TLSv1-CONNECTION - LOG_SSL_LEVEL - ACCEPT Client: [IP::client_addr] [SSL::cipher version] - [SSL::cipher name] - [SSL::cipher bits] - For the VIP - [virtual name]"
}
}
AltocumulusIn that case i have many VS with the same SSL profile and I wanted to know if it was possible to do it with an irule.
I will try the suggested irule.
Thanks
MVPhere is a link that shows you how,:

you do it from SSL CLient profile.
AltocumulusHi Mihaic,
Thanks for your responce.
I have allready read the suggested article but i want to disable TLS v1 & TLS v1.1 only on a specific virtual server without disable TLS v1 & TLS v1.1 in the SSL profile.Is it possible with an irule for example?
MVPCreate a new SSL-Profile and use your current one as parent. Then deactivate tls1/1.1 and put this on the virtual server.
MVPtry this irule:
when CLIENT_ACCEPTED {
SSL::profile vip_ssl_no_TLSv1
}
where vip_ssl_no_TLSv1 is another SSL profile where you disable whatever you want.
I tested with this cipher string : DEFAULT:!TLSv1:!TLSv1_1
AltocumulusIt works!
Thank you for your support.
