NimbostratusHi Guys, need your insight here. I have a simple topology as this: browser 10.0.1.244 -> vs 10.0.1.204 pool 10.0.2.101 and 10.0.2.101 has a static route 10.0.1.244 255.255.255.255 10.0.1.204 I can only make this work with automap on. If I choose source address translation as "none", the vs stop works. I can see traffic in/out from vs but only in from pool, no out. tcpdump proves it. Could anyone help me on this one?
NimbostratusChange your route on the server (10.0.2.101) for 10.0.1.244/32. The next-hop should be the BIG-IPs self-IP (floating, if available) in vlan 10.0.2.x, not the VIP for the VS.
I'm making some assumptions based on lack of info, but I assume your BIG-IP and server (10.0.2.x) are on the same network.
The route that you have specified (10.0.1.244 255.255.255.255 10.0.1.204) has a next-hop that is not on a directly-connected network of the server. This won't work unless the server can recursively find a route that provides a next-hop on a connected network. I'm assuming your BIG-IP has a self-IP in the 10.0.2.x network, as when you enable auto-map the BIG-IP will (preferentially) SNAT traffic to the floating IP on its egress VLAN.
CirrostratusHello Joe,
If you don't want to use Automap, the only thing you need to change is your backend server (node) default gateway.
Please set it to F5_Floating_Internal_Self_IP_Addr and try again. In this way all response from servers will be routed by the BIG-IP.
Regards
