Description of problem:
LoadBalancer Internal-IP and EXTERNAL-IP are not accessible from Windows workers
Version-Release number of selected component (if applicable):
9.0.2-f8d49fb 4.14.0-0.nightly-2024-05-07-214708
How reproducible:
100%
Steps to Reproduce:
1. install WMCO 9.0.2 2. install 2 Windows machineset 3. install Windows service, Linux service, Windows workloads and Linux workload 4. From windows pods access the Linux server e.g. curl <IP>:8080, access Windows clusterIP
Actual results:
Linux service is not accessible from Windows nodes win -> Linux Internal-IP does not work > oc exec win-webserver-66b77f88bc-8pg7s -- curl 172.30.244.252 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- 0:00:21 --:--:-- 0 curl: (28) Failed to connect to 172.30.244.252 port 80 after 21028 ms: Couldn't connect to server command terminated with exit code 28 Linux -> win Internal-IP works > oc exec linux-webserver-568f44c48-5wz4r -- curl 172.30.137.127 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 63 100 63 0 0 2012 0 --:--:-- --:--:-- --:--:-- 2032 <html><body><H1>Windows Container Web Server</H1></body></html>% win -> Linux EXTERNAL-IP does not work > oc exec win-webserver-66b77f88bc-8pg7s -- curl 34.172.194.34 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- 0:00:21 --:--:-- 0 curl: (28) Failed to connect to 34.172.194.34 port 80 after 21043 ms: Couldn't connect to server command terminated with exit code 28 Linux -> win EXTERNAL-IP works > oc exec linux-webserver-568f44c48-5wz4r -- curl 34.171.167.234 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 63 100 63 0 0 13378 0 --:--:-- --:--:-- --:--:-- 15750<html><body><H1>Windows Container Web Server</H1></body></html>
Expected results:
