L7 https ACL with APM SSL VPN not working
Hi, I am building a POC for Client SSl VPN with F5 APM in AWS. Since we are using AWS I would like to use L7 ACLs instead of L4 since IP addresses keep changing in AWS. I got it working for http but not for https. In another post I found this: https://techdocs.f5.com/kb/en-us/products/big-ip_apm/manuals/product/apm-config-11-4-0/apm_config_resources.html147209 You can use a Layer 4 or Layer 7 ACL with network access, web applications, or web access management connections, with the following configuration notes. With network access, you can use a Layer 7 ACL that is configured to provide access control for port 80 HTTP connections. However, if you want to provide access control for anything that is not on port 80, you must create a second virtual server, configured with the IP address to which the ACL entry applies, and the default access profile, access. For HTTPS network access connections, you can use Layer 7 ACL entries only if the virtual server has the private key of the backend server. Does that really means I will have to create an additional VS for every single URL I want to access via https and also need the key for that URL? I hope not. Thanks.

APM Deny ACL Blocking Portal Access Resources
I hoping this is an easy one.. I have added a deny all ACL to an access policy, ensuring that it is last in the ACL order. However it is blocking portal access resources - with configured resource items. My understanding is that providing the user defined deny ACL is processed after the ACEs that make up the portal access resources, then access to these resources should be permitted. Am I missing something?? Thanks MP
Challenges with limiting traffic
hi, im currently working on a remote access solution for a customer. The basics have been set up and works(apm and vpn), but im now struggling with trying to narrow down the access for remote users. Remote users should only be allowed to access ip addresses ending with a specific number, as a means to limit access beyond the applications they service. In addition, remote users should only be given access to resources they should, and not be able to access ip addresses they dont work on. Are there any ways to implement such a solution through apm? I have looked at ACL, but static will probably be to manual for the customer, and i havent worked with dynamic ACL's before, so not sure how to set this up properly. As a test, would it be possible to create a static ACL, or some other form of check, that will allow users access to the correct ip address, if the last octet matches?
A simple source-ip whitelist and blocking page on HTTP pages?
Hi all, I need to do some whitelisting on a http virtual-server for some source-ip's and for all other ip's there should be a html blocking page displayed to the user. No iRule should be used for this, since the config needs to be simple. I checked with AFM. It is possible but no response page with source-ip filter. I checked ASM. But it seems to complicated since I don't need ANY other filtering, only source-ip acl. I checked protocol security profile but no possibility to combine a blocking page with AFM. Any ideas how to do this on a simple way with the advanced firewall on F5? Thanks, PeterAPM dynamic ACLs attached to AD or LDAP groups
Hi, I am building a client vpn setup with F5 APM. It's working quite good so far. I have a static ACL configured for now. I would like to use dynamic ACLs in the future so managers can give their Team members access themselves by adding them to specific ldap or AD groups (we use both). My question is, is this even possible? Can I add ACLs to groups? And if yes, how does the F5 then knows which groups it should read ACLs from, since a user could be in different groups. The groups would be preconfigured in LDAP/AD and all ACLs would be configured on the group. e.g. Sales guys need access to specific tools. I would create a group in LDAP/AD for this purpose and add the appropriate ACLs to this group. The manager could then add his Team members to this group and thus the Group members have access to the needed services. But the user could be also in many other groups. I was thinking about some sort of naming convention for the groups. Like acl-sales, acl-internet-access. So the F5 only looks in groups that start with acl-. Hope you understand my question and I have understood dynamic ACLs correctly. Thanks in advance.[APM] ACL Interest
Hi, I'm integrating VPNSSL F5 by using APM since many week. Our users population are susceptible to use the following elements : Portal Access RDP Access Network Access My questions are about Network Access. Today, I use Network Access to allocate the same IP address inside and outside the entreprise (F5 has in interface in all my entreprise LAN). After that I have as many Forwading VS than Entreprise LAN. On each forwarding IP I've I this irule : when CLIENT_ACCEPTED { if { [IP::addr [IP::client_addr] equals 192.168.160.0/255.255.254.0] } { node 192.168.160.1 } else { log local0. "[IP::client_addr] access problem" reject } } This Irule send to gateway 192.168.160.1 if the Network Access IP is in 192.168.160.0/23 range. This system works perfectly but i've questions about that : I've have an ACL that looks like this : Src : 192.168.160.0/23 Destination : 0.0.0.0 Port : Any Allow My firewall are here to do filtering, not APM. Since this morning I realized that if I remove this ACL, nothing change, all works perfectly too. My F5 is not supposed to filter if there is no ACL ? In this case, what is intereset off ACL (only portal mode) ? Thanks a lot for yours answers
APM + Cisco ISE and Dynamic ACL
Hi there, I'm trying to assign user based ACLs downloaded from Cisco ISE everytime a user logs in however I get the error "ERR_PARSER_UNSUPPORTED_TOKEN" and it is not working. I followed the F5 guidelines here. I tried a simple scenario with a single entry ACL but still not works. How can be this implemented? Thanks.
APM ACL what is source for IP evaluated
Hi, I am struggling with figuring out what is base for IP evaluated by for example Static ACL in APM. As far as understand ACL object in VPE are only evaluated during Access Policy processing (between ACCESS_SESSION_STARTED and ACCESS_POLICY_COMPLETED) but using ACCESS_ACL_ALLOWED (or denied) I can use ACCESS::acl eval to doper request ACLs. Question is what is used as src and dst IP for ACL evaluation? Is that one of Access Policy variable or actual IPs based on flow? I am asking because I would like to create ACL for forward proxy VS - in this case I can see client IP as src IP but dst IP is VS IP not target server IP (proxy is doing DNS on HTTP proxy request URI - like GET http://www.site.com/something/index.html HTTP/1.1) so in L3/L4 there is no real dst IP known. My idea was to use host from HTTP proxy URI ( do DNSresolveand pass it to access session variable so ACL can use it to evaluate - but not knowing if evaluation is based on session variables makes me wonder if this will work?
