Cant ping internet from F5 Big-IP

Hi, Am setting up F5 WAF in AWS. The nodes are up and am able to ping VIP Ip adderss from outside. But I cant ping outside from the F5 and it doesnt fwd the packets received at the VIP to the internet. eth2 is my interface facing the internet. It has auto assigned IP - 10.0.1.26 and I added secondary IP for VIP-10.0.1.27 and created the VIP with this IP and enabled to the vlan V13(internet facing). When I try to ping something like -I V13, I get Destination Host Unreachable. Can someone tell me what am doing wrong? thanks
