F5 BIG-IP - SNAT mini-lab

Webserver IP 10.10.11.101 (I disabled all pool members apart from this one for this test)
F5's internal floating self-ip: 10.10.11.5
Hosts IP (VM on a PC so its VMNIC3's IP): 192.168.242.1


Using SNAT automap you should see the internal floating self-ip address of the F5 when you run a netstat on the webserver:



netstat --tcp --continuous -n
















Notice the foreign address is the F5's internal floating self-ip of 10.10.11.5


 

















Using no SNAT




netstat --tcp --continuous -n














I forgot I had snatted all vlans to 172.16.32.1.  Looks like that worked too ;)




















I'll turn that off... have to delete it actually...one sec...





Thats better...















192.168.242.1 is VMNET3 (aka my PC)






Job done ;)
