Confirm design relying on auto_lasthop
Can someone confirm my proposed configuration will work as desired?
I have a need to configure the BigIP to load-balance http amongst a
cluster of proxy servers. Non-http traffic is forwarded straight out,
thus we are using a vlan group to create a layer 2 bridge. It is
important that the client IP is preserved all the way, both in the BigIP
and in the proxies.
Client----- Router1 --VLAN1-- BigIP --VLAN2-- Router2 ----- Internet

VLAN3

Proxy1 Proxy2 Proxy3
BigIP is a transparent bridge: VLAN1, VLAN2, VLAN3 are in a VLAN group.
non-port 80 traffic is forwarded from vlan1 to vlan2.
A virtual listening on vlan1, 0.0.0.0:80 load-balances to one of the proxies on vlan3 (no SNAT)
Proxy creates a new connection with original client IP and forwards to Router2.
Will auto_lasthop forward replies to the original proxy?
