Dear all, I would like to implement ssl brigding for SMTPS traffic in my organization. In my case, I would like the client devices to receive the certificate configured in clientssl profile. When adding the serverssl profile to the virtual server, I get an error: smtps configuration error: SSL forward-proxy must be enabled Configuring SSL forward-proxy is not a solution for me, because the clients do not accept SMTP server certificates. Is it possible to configure ssl bridging for SMTPS without configuring SSL forward-proxy or to configure SSL forward-proxy so that client device get the certificate defined in clientssl profile?18Views0likes1CommentGet actual client ips in splunk

Hello When the security team starts Vulnerability Assessment and Penetration Testing (VAPT) or Application Security Testing (APT) on a web application, then it can go and test those web pages that only registered users can browse. Is there any way I can block this with Big-IP. Sorry if my question is silly.39Views0likes7CommentsHigh CPU utilization (100%).
I observed high CPU utilization (100%) on F5 device, resource provision ASM nominal. I checked the client-side throughput and server-side throughput both are normal but found management interface throughput is very high and what i noticed this is happening in same time period for last 30 days. What could be the reason for this spike. Many thanks in advanced for your time and consideration.129Views0likes14CommentsReclaim disk space for BIG-IP tenants running on rSeries systems

Is it okay to remove ssh/tcp 22 off the allowed list on the self IP after running gtm_add/bigip_add/big3d_add or does it need to stay there? I know 4353 has to stay, but I can't find anything that says it's okay for 22 to go away.Solved39Views0likes1CommentASM don't block attack XSS
