Referencing a VIP as a pool member
I’m having problems getting a VIP to reference another VIP on the same F5. I’m using auto-map SNAT which appears to be working correctly (by looking at TCP dump). I’ve now discovered that it is sending the traffic destined to the VIP to the firewall which is dropping it.
My setup is as follows
VIP of http service: 172.29.50.30
LB self IP: 172.29.48.248
LB float IP: 172.29.48.250
Pool member having issues: 172.29.50.3
The VIPs in the 172.29.50.0/24 range don’t make it into the F5’s routing table, so when 172.29.50.30 tries to call 172.29.50.3, it does the SNAT and the source become 172.29.48.250, but follows the default route (the firewall) rather than talking to “itself”. If I try to add a route for 172.29.50.0/24 via 172.29.48.248 or .250 it says I can’t use a self-IP. Any ideas? Can I somehow declare the 172.29.50.0/24 range to the F5 so it knows it owns it?
I'm running 11.2
Thanks!
