Changed behaviour after after supposedly successful migration
We just replaced six older F5s (1500, 1600 and 3400 from 2005 and 2008) with 2 F5 Big IP 4000 using partions to separate the rulesets. Everthing works fine, just a minor inconvenience showed up, as the (http-) traffic forwarded to the servers via firewall shows as source ip the floating ip of the big ips in the vlan instead of the self ip as it was in the past. I tried to compare the configuration (9.4.3 on the 3400, 11.5.1 HF4 on the 1600s, 11.6.0 HF3 on the 4000s) as best as I could but didn't find something obviously different except the changes coming from another version or using a LACP-trunk now. I thought it might be something like SNAT automap on but we never used this.
Any suggestions what might cause this change of behaviour?
