asm
93 TopicsHigh 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.25Views0likes2CommentsHSTS is not working.
Hi there, We have one irule is configured on VIP which is redirecting to maintenance page if user access the wrong url on that page HSTS is not working but if we access the right url then HSTS is working. We have enabled HSTS in http profile and that is attached to the same VIP with irule. Is there any way to enable HSTS on maintenance page or any remediation to fix that issue. if { $DEBUG } { log local0. "TEST - Source IP address: [IP::client_addr]" } switch -glob $uri_ext { "/httpfoo*" {set uri_int [string map {"/httpfoo" "/adapter_plain"} $uri_ext]} "/httptest*" {set uri_int [string map {"/httptest" "/adapter_plain"} $uri_ext]} default { HTTP::respond 200 content [ifile get ifile_service_unavailable_html] set OK 0 } } Many thanks in advance.Solved85Views0likes1CommentMigration from physical Hardware to R series

Dears, I have following scenarios, 1. if Traffic from Internal user/IP --- >Allow connection 2. Traffic from internet 2.1) Block access only on Host name ( URL ), That is -----> https://XYZ.com 2.2) Allow access to URI's, Thats is ------- > https://XYZ.com/abc or https://XYZ.com/* I tried multiple way and find some solution but its not working. Its great if some one helps here when HTTP_REQUEST { set reqBlock 0 if {[string tolower [HTTP::host]] eq "XYZ.Google.com" && [IP::addr [IP::client_addr] equals "10.0.0.0/8"]} { log local0. "[IP::client_addr] triggered geo" set reqBlock 1 } } when ASM_REQUEST_DONE { if {$reqBlock == 1} { ASM::raise VIOLATION_URL_GEOLOCATION } }46Views0likes1CommentF5 ASM Response logging show different timezone from Request logging
Dear All Respected Members, I have a question on f5 AWAF response logging. I am setting up a WAF policy to block attacks and monitor all traffic to and from the real servers. I can see the logs generated for both request & response, but it shown incorrect log timezone for responses. BIG-IP, real server and client are set local time zone GMT+7, but the repone logs are GMT. I have double checked timezone on all devices are configure correctly. Could you advise me what is the root cause and how to fix it? Thanks.144Views0likes2CommentsWAF for APM Oauth Authorization VS
Hi, We are testing the using of F5 as a OAuth Authorization Server and also a Resource Server. We have a WAF policy attached the VS representing of the Resource Server, which has an IIS server behind it. Since VS of the Auth Server will only utilize APM capabilities and won't actually have any application/web server behind it, I'm wondering if it's advised to add a WAF policy for this VS. I was told it's not necessary but I find it odd, since attackers can still try to attack the F5 itself. Any thoughts?Solved175Views0likes7CommentsHA Configuration (One in primary and One in DR)
Hi folks, I currently have HA pair (active/passive) in a primary data center and we are bringing up a DR. wondering can I split up the HA pair (One in primary and One in DR) and continue to have HA with utilizing different subnets? We are using multiple IPSEC tunnels to connect the sites so we are still working on whether we can extend subnets but if we can't I wanted to ask if different subnets are possible. Thank you any info is appreciated48Views0likes4CommentsASM Sync Between 2 Data Centers
