IPV6 Forwarding virtual server not working

Hi,

 

I am trying to create a forwarding virtual server that uses an irule to snat my backend servers IPV6 to a specific IPV6 depending on the network destination. From my backend server IP: fc01::a00:0:97. I tried to ping IP: 2001:123::1 - I am monitoring the ltm log (tail -f /var/log/ltm) and I do not see anything going thru my virtual server (I am not hitting that virtual at all). Can anyone shed some light on this- Thanks in advance - Farid.

 

Here is my config:

 

ltm rule /Common/ipv6Snat_rule { when CLIENT_ACCEPTED { log local0. "Client IP: [IP::local_addr]" if {[class match [IP::local_addr] equals IPV6_NETS_DG ]} { log local0. "Using SNAT ip: 2001::2:ff" snat 2001::2:ff } else { log local0. "Using SNAT ip: 2001::1:cc" snat 2001::1:cc } } }

 

ltm data-group internal /Common/IPV6_NETS_DG { records { 2001:123::/64 { } } type ip }

 

ltm virtual /Common/IPV6_FWD_VS { destination /Common/::.0 ip-forward ip-protocol tcp mask any6 profiles { /Common/fastL4 { } } rules { /Common/ipv6Snat_rule } translate-address disabled translate-port disabled vlans { /Common/INTERNAL } vlans-enabled }

    Try the below

    when CLIENT_ACCEPTED { 
if {[class match [IP::client_addr] equals IPV6_NETS_DG ]} 
{ snat 2001::2:ff } 
else 
{ snat 2001::1:cc }

}
