We are doing our actual implmentation of the F5 BigIP LTM VM version 17.1.03 (build 0.0.4). It's a little bit complcated because we are trying to load balance an application (Microsoft Dynamics Navi...
Currently the BigIP only has 1 pool member, msnav01.domain.com (I've disabled the other one for testing). If I go direct https://msnav01.domain.com I get the IIS welcome page so I'd expect if the BigIP were working correctly, if I go to https://bigip.domain.com (which can only load balance to msnav01.domain.com) I should be seeing the IIS welcome page.
irbk To make sure I understand. The URL "https://msnav01.domain.com" points directly to the server and URL "https://bigip.domain.com" points to the F5 virtual server? If you are not seeing the IIS page when going to the bigip domain it's most likely that the server is not configured to respond to host "bigip.domain.com" but "msnav01.domain.com" which is why you are receiving the error. Try editing your hosts file to point "msnav01.domain.com" to the IP of the F5 virtual server and see if you are having the same issue. This still seems like a server issue because 404, unless otherwise configured, would only come from the server and not the F5. If you open of dev tools in your browser you can view the HTTP header field "Server" and it will most likely show some variation of "IIS" as the value rather than "BIGIP" which would imply you are making it to the server.
Well, this whole thing may have been a red herring. paulj Yes, your understanding correctly. What I've just realized is that while going to https://msnav01.domain.com brings up an IIS welcome page going to https://<ip of msnav01> does NOT bring up an IIS welcome page <facepalm>. Just to test, I found another server that DID bring up a page when you went to https://<test ip> and created a new pool for the <test ip> and then adjusted my VS to use the new test IP pool and the thing worked. So it seems like this whole thing was a failed assumption. I should have verified that https://<ip of msnav01> also brought up an IIS welcome page.
