APM Policy with Restrict to single client IP
I am using an APM policy for RDP connection authentication. Currently, there is no pool associated with the VIP, and the client-server connection is defined within the access policy. For users connecting from an ISP, the IP address keeps changing, which causes their connections to be terminated, as shown by the error below. In the access policy, there is an option called "Restrict to single client IP". When we disable this option, the connection works, but this feature is crucial for protection against Session Hijacking. Have any of you encountered a similar scenario? Or do you have any suggestions on how persistence could be achieved without compromising security, perhaps using an iRule or other solutions?
Client SSL Profile set to Require Client Certificate breaks RDP in APM
Hello, I have a policy set up in the BIG-IP F5 VE 15.1.10.5 APM to allow access to a handful of Remote Desktop (RDP) links. I'm attempting to set the authentication to require Common Access Card (CAC) Certificate login. In my access policy visual editor, I have a Client Cert Inspection branch that leads into OCSP Authentication and then if successful assigns the RDP resources through LDAP. This all works perfectly fine as long as the Client SSL profile connected to the access policy has Client Authentication > Client Certificate set to "Request" or "Require." If set properly, when a user attempts to connect to the webtop URL they are prompted for their certificate, authorized against the OCSP, and given access to the resources as corresponds to LDAP group. However when attempting to use one of the Remote Desktop Links it'll download the RDPconnection as intended and fail to connect with "There was a problem connecting to the remote resource. Ask your network administrator for help." I know this is because of the Client SSL profile because if i change it back to "Ignore" and have the user click the Remote Desktop link, it downloads and connects to the specified resource with no issue. The server the RDP connects to is configured with a client certificate that is trusted by the Root and Intermediate CA in the "Trusted Certificate Authorities" under the Client SSL Client Authentication profile. I was originally able to get around this by, instead of using Client Cert Inspection in my access policy, using On-Demand Cert Auth and leaving the Client SSL profile to "Ignore" client certificate. This allowed the user to be prompted and authenticated when originally accessing the webtop and utilize the RDP resources assigned. Unfortunately, On-Demand Cert Auth recently broke and users are not being prompted for their certificate and as such cannot connect to the webtop without the Client SSL profile being set to "Request" or "Require" to force the certificate prompt. https://my.f5.com/manage/s/article/K63123740 I've read the above KB where it says "the RDP client doesn't like the certificate request." but I'm not sure why, RDP should support certificate requests, users authenticate with token certificates all the time when RDP'ing to resources unless I'm misunderstanding what is happening? With that article I thought maybe the Server SSL profile would be an issue, but only changing the Client SSL profile certificate settings affects login. Any help would be appreciated, thanks!

F5 webmail exchange 2016 - "Access policy evaluation is already in progress for your current session."
We recently moved over to outlook 2016. Users that are on 2010 connect fine and never have an issue. the new users that have moved over to 2016 mailboxes get the error message above in the title. When they connect, they get the following addons to their URL: ?bO=1 sessiondata.ashxappcacheclient=1&acver=15.1.1591.8&crr=1 I have tried irules from the following devcentral questions and answers with no success: Access policy evaluation is already in progress for your current session How to avoid "Access policy evaluation is already in progress" - (irules from matt, Misty Spillers & Stanislan Piron tested and didn't help) If i have users open a browser in "InPrivate Browsing" or "Incognito" mode, they don't get the error. I have also tried the windows_10_anniversary_fix as well as all the irules on page 76 of the iapp deployment guide for exchange 2016. Deployment guide stuff i tested and doesn't work: when HTTP_REQUEST { if { [HTTP::cookie exists "IsClientAppCacheEnabled"] } { HTTP::cookie "IsClientAppCacheEnabled" False } } and tried this: when HTTP_REQUEST { if { [HTTP::cookie exists "IsClientAppCacheEnabled"] } { HTTP::cookie remove "IsClientAppCacheEnabled" HTTP::cookie insert name "IsClientAppCacheEnabled" value False } } I have a ticket open with F5 but they are saying oh just check the guide. not helpful. Hoping someone from the community can help me. thanks in advance!APM Access Policy - Pass LDAP or AD Query variable
Is it possible to query whether a user has a value for one or another variable then use that to pass or fail passage down the rest of the swimlane for access? (e.g.- expr {[mcget {session.ad.session.ad.last.attr.variable1}] != 0 || [mcget {session.ad.session.ad.last.attr.variable2}] != 0} where the two variables are numbers or a non-constant string, but do have a value...and are not "<not set>". Is it also possible to have another path where the lack of a value for the expr {[mcget {session.ad.session.ad.last.attr.variable1}] == 0, can be sent to a uri or url? Any assistance would be greatly appreciated!ACCESS::policy result "not_started"

Branch evaluation fails with Rule evaluation error: invalid command name "session.logon.last.username"
Hopefully somebody is able to enlighten me, I have the code below in a branch rule expression of an AD Query element. I get an 'Rule evaluation failed with error: invalid command name "session.logon.last.username"' error. The purpose is to translate an email entered to the matching AD logon username from AD. The AD query succeeds (mail=%{session.logon.last.username}). It looks like the variable assign element is not able to change the session.logon.last.username variable. if { [mcget {session.ad.last.queryresult}] == 1 } { session.logon.last.username = mcget {session.ad.last.attr.sAMAccountName}; return 1; }; return 0; Thanks for sharing your thoughts / ideas.
Windows Group Policy Trigger on Network Connect
Hi, I'm wondering if there is a way to trigger Windows Group Policy to be triggered when a user connects to VPN. We are able to run gpudate.exe as an application on connect, but this is visible to the end user. We have User and Machine Windows Group Policies on our domain which we'd like to ensure gets applied once the user is connected to VPN and not have to wait for the usual Windows GPO refresh cycle.
