Hi all, Can anyone help me understand how to configure VIPs SSL Passthrough, SSL Offloading and SSL Bridging scenarios? What components are taken into consideration for each of the requirement as in VIP type, Pool member health monitor, Client and Server SSL profile, Client and Server Protocol profiles, HTTP profile and persistence if any. Thanks.13KViews1like1CommentOffline (Enabled) - The children pool member(s) are down
Hi Friends, I am novice to F5 and following CBT Nuggets to understand LTM in a better way. I have completed basic configuration i.e defined Nodes, defined Pool and assigned Pool Members to my Pool. Now the problem is that I have enabled "http" health monitor and right after I click 'finished' the icon Transitions from 'Blue Square' to 'Rectangle Red' - Offline(Enabled) - The children pool member(s) are down when I hover over the Pool in 'Pool List'. Now this is a very basic setup with 3 .OVA web servers pre configured which I received in my Nuggetlabs. I am able to login to the servers using my browser, telnet 10.2.0.11 80 and curl http://10.2.0.11 commands but the Servers are showing as Offline(Enabled) - Pool member has been marked down by a monitor in 'Members' list. I need your help to proceed further please. Thanks in advance, SagarSolved8.5KViews0likes10CommentsHow to display the whole configuration of a BIG-IP with default value ?
Hi Guys, I'm currently seeking the CLI command or a way to display and get the configuration of a BIGIP with all default values include in the configuration file (bigip.conf). I'm not sure if it's possible with F5. Thanks for your experience. Morgan7.7KViews0likes2CommentsVLAN Tagged vs Untagged. What does this mean.
I have two interfaces 1 and 2 and decided to use 1 for internal traffic and 2 for external traffic. Both Vlan and untagged. Should one be tagged or not. I don’t see any communication from the External vlan TCPDump . I don’t get any communications TCPDump on the external vlan arp. What exactly does this mean.4.9KViews0likes4CommentsSSL VPN Disconnect Issue
We currently have an issue with our SSL VPN connection disconnecting on random intervals. I do have a open support case and unfortunately not making any drastic headway, so reaching out here to see if anyone has had this issue or possibly something else I can try. We previously were using Juno Pulse and did not have this issue with any clients. I am able to re-produce the disconnect by doing a simple file copy from one of our systems to my PC. Below is all the information that shows in the APM log, unfortunately there does not appear to be any further debug with PPP tunnels. 2014-08-15 06:59:05 Assigned PPP IPv4: 192.168.0.57 Tunnel Type: VPN_TUNNELTYPE_TLS NA Resource: /Common/VPN 2014-08-15 06:59:05 PPP tunnel 0x57025106e400 started. 2014-08-15 07:10:07 PPP tunnel 0x57025106e400 closed. Next we went to wireshark where we are seeing a lot of TCP zero window packets, so I set the zero-window-timeout to infinite to rule out zero window disconnects. The issue still occurs after making this change. Currently I am working on a client side capture to compare with the tcpdump on the appliance, but I am not seeing anything in the capture that stands out as a red flag (I am no wireshare expert by any means so digging though these captures is pretty slow). Any thoughts or information is greatly appreciated, also please let me know of other info that would be of use.Solved3.8KViews0likes18CommentsCan't ping active LTMs self ip or floating ip
I have two 2000s (F5a and F5b) in an active/standby configuration. TMOS version = 11.5.2HF1 There are 2 VLANs. Internal, External, HA. My problem is on the internal vlan. On the internal-vlan, F5a-self-ip = .163 F5b-self-ip = .164 Floating-ip = .161 From the upstream L3 switches, I can ping .164 but cannot ping .163 or .161 When I force F5a to standby, the problem reverses. Now I can ping .163 but not .164 or .161 It appears I can only ping the standby unit's self ip. The other two do not respond. On the external VLAN, everything pings fine. Anybody have any thoughts on what may be occuring here? port-lockdown is set to allow all. Thanks!!3.5KViews0likes8CommentsHow does MAC Masquerading work exactly?
Hi, I am trying to grasp how exactly MAC Masquerading works, and how it behaves differently during a failover. Situation without MAC Masquerading Every floating Self IP & virtual IP will have a gARP anouncement with the new MAC address issued on the device becoming active, making the switches now route to the new device. Issues can arise if network equipment cannot handle the amount of gARPs. Situation with MAC Masquerading Every floating Self IP in the cluster has the same MAC address. Not sure about the vIPs. During failover, the switches need not learn a new MAC address but just learn it's now available on a new switch. (in our case, L3 switches with OSPF) So how do vIPs fit in the mac masquerade story? And how do switches learn the vIPs/floating Self IPs are now on this port without gARPs? The DevCentral articles do not discuss this in great detail.3.1KViews0likes1Comment
