Is there Limitation of irule "virtual".. can we do it like this?
Hi We have BIG-IQ and BIG-IP AWAF. I see that BIG-IQ application dashboard is show only 1 application per virtual server. But in BIG-IP AWAF.. we config it as 1 virtual server 100 application (multi domain vip+use irule to check host header and send it to specific pool and choose specific waf policy) So we can't see each application metric in BIG-IQ.... This is our issue. I understand we need to config each vip for each application so BIG-IQ can retrive data from each vip per application but we can't use that many public ip. So I found that we have irule "virtual" which can send traffic to another virtual server. Can we do it like this? Instead of when HTTP_REQUEST { if {[HTTP::host] equals "abc.example.com"} { ASM::enable /Common/abc.example.com >>>> choose pool and waf policy by host header pool /External/Pool_abc.example.com } ------------------------------------ Change to when HTTP_REQUEST { if {[HTTP::host] equals "abc.example.com"} { virtual VS_abc.example.com >>> send it to private ip virtual server by host header which craete a new. } and in virtual server VS_abc.example.com we use private ip and assign pool and waf policy normally so we can add VS_abc.example.com in BIG-IQ application dashboard and see metric per application. But is there any limitation on how to use irule "virtual" like this? Is this practical?
ssh authorized_keys softlink missing on F5 Node1
Hello, Need clarification regarding with authorized_keys missing softlink! The difference is that there is a softlink to ‘/var/ssh/root/authorized_keys’ on Node2, which is not on Node1. My question is, why is there such a difference with Node1 and Node2. Any idea?

SSL issue
Hello there, We have a F5 LTM and a virtual server configured to a server in port 443, the topology is: Computer --> F5 LTM --> switch --> server When we try to connect to the server through https we saw the message "Connection reset" in the browser, but if we try to connect without passing the F5 the connection is successful. We don't have configured any SSL client profile or server. This is the configuration on F5: #Virtual Server #________________________________________________________________________________ ltm virtual /Common/Server1 { destination /Common/10.1.5.X:443 ip-protocol tcp mask 255.255.255.255 pool /Common/Server1 profiles { /Common/tcp { } } source 0.0.0.0/0 translate-address enabled translate-port enabled } #________________________________________________________________________________ #Pools #________________________________________________________________________________ ltm pool /Common/Server1 { members { /Common/10.1.7.X:443 { address 10.1.7.X } } monitor /Common/https_443 } #________________________________________________________________________________ #Profiles #________________________________________________________________________________ # -Default Profile- ltm profile tcp tcp { ack-on-push enabled close-wait-timeout 5 congestion-control high-speed deferred-accept disabled delayed-acks enabled ecn disabled fin-wait-timeout 5 idle-timeout 300 keep-alive-interval 1800 limited-transmit enabled max-retrans 8 nagle disabled proxy-buffer-high 49152 proxy-buffer-low 32768 proxy-mss disabled proxy-options disabled receive-window-size 65535 reset-on-timeout enabled selective-acks enabled send-buffer-size 65535 slow-start enabled syn-max-retrans 3 time-wait-recycle enabled time-wait-timeout 2000 timestamps enabled } As you can see, we don't have any SSL client or server profile and we tried changing "translate-port" to disabled and "Source Address Translation" to auto map but none of these work. Also we made a tcpdump and we can see the TCP Reset from 10.1.7.X (tcpdump.png) and some curl (curl.png), openssl (openssl.png and openssl2.png) and a telnet (telnet.png). Hope you can help us to find out what's going on. Thank you.
