Hello community!
Question is changed as I got more details
I'm facing strange issue with F5 LTM. ver: #TMSH-VERSION: 14.1.4
We have Virutal servers configured on specific ip and port for UDP traffic (syslog on port 514)
When we run tcpdump on F5 we see following behaviour:
It looks like there is some kind of loop created by F5 but we do not see configuration that could lead to this behaviour.
Any ideas? What component/configuration could lead to such loop?
We have other VIPs for the sme ip with different ports but similar configuraiton.
We do not have any wildcard VIP
ltm virtual /Common/VIP_UDP_514 {
description VIP_UDP_514
destination /Common/10.1.1.66:514
ip-protocol udp
mask 255.255.255.255
pool /Common/Log_Collector_UDP_514
profiles {
/Common/udp { }
}
source 0.0.0.0/0
translate-address enabled
translate-port disabled
}
