DNS requester default domain
Hi Devcentral, I have just configured a new VS to use as a proxy server using the http-explicit profile. Everything works fine except for one kind of request. When a user asks for an internal web site without using the FQDN. In this case the 'DNS-Resolver' in the LTM configuration will ask the DNS for this hostname adding just a .(dot) at the end as if it was a top-level domain. In my case, I would like to be able to add a default domain to search from. For example, when a user browses for i'd like the 'DNS-resolver' to ask for "intranet.local." instead of just "intranet." The "DNS Search Domain List" in the System›Configuration>Device>DNS is configured but seems to be used only by the linux/mgmt part of the big-ip not by the LTM. So I have wondering if there is a hack for that because I can't find it in the GUI. Please let me know. Regards, Stephane
How Destination persistence works?
Basically I don’t get which dst is would be used. The one on the vs or the ip of the pool members after auto map? And how will a client ever get the same pool dst ip for the persistence to work if a load balancing algorithm would be executed before choosing the pool members?
DHCP Relay not forwarding traffic
I'm Testing DHCP relay on our F5. I have followed the following guide. https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-1-0/23.html Host Network range is 10.10.0.0/24 VLAN55 DCHP servers are on 10.11.0.0/24 LAN56 10.11.0.3 and 10.11.0.7 When setting up the Virtual Server I had to change the source from 255.255.255.255 too 0.0.0.0. Type DHCP relay was not available, just DHCP (same thing?) tcpdump on VLAN55 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:50:56:96:01:7a, length 300 in slot1/tmm0 lis=/Common/dHCPRELAY No traffic destined for the DCHP servers on VLAN56 IP 10.11.0.3 > 10.11.0.5: ICMP echo reply, id 8976, seq 6684, length 20 in slot1/tmm2 lis= Statistics show, IN OUT IN OUT dHCPRELAY Common View... 341.1K 0 130 0 1 1 1 0 0% 0% 0% No Data No Data No Data I have tried using both profiles, dhcpv4, and dhcpv4_fwd same results. any ideas? thank youNeed understanding of HTTP compression profile.
Hi, I have question with HTTP Compression profile. My LTM running on 12.1.2 where HTTP Compression enable on one of the Virtual Server serving web requests. Web administrator requested us to perform compression on LTM for specific URI only so we added few URI in list. i.e. URL is , we have added /test in URI List. Content Compression is selected as "Not Configured". So my question is Whether compression works on not? If it works, it will compress all the content type served under /test/* ? How LTM behaves for content already received from server in compressed form? Very limited knowledge with compression hence need some inputs. I have read F5 online article but still need some clarification. https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-profiles-reference-11-6-0/3.htmlunique_1659057140 Thanks in advance.

Migrate from 11.6.1 to 12.1.2
We purchased 2 new i4000's. I would like to migrate my configuration, including virtual servers etc from the old units running 11.6.1 to the new units running 12.1.2. I would like to migrate my ASM security policies as well. Is there a way to do this? When I try using the platform-migrate option I see: Installing configuration... ERROR: Module ASM is invalid for platform-migrate mode. Only LTM and GTM are supported. Is there a way to do what I would like to do?
iRule to change base href="http:// to base href="https://
Can anyone give me a hand changing the Base Href from http to ssl? The developers have some code that says if the request is http then set the base to http and if it's ssl change the base to ssl. Unfortunately, my traffic from f5 to server is http so I want to use an iRule to change this base reference. Any help, would be Very Much appreciated!!! TIA Scott
