Altostratusunable to ping VIP from server with the F5 as the DGW
so if it was suggested and I didnt see it I apoligize. The fix for me was to go to the virtual server that I was trying to access from the host nework (10.1.228.x) which used the F5 as its gateway and add the VLAN to the VLAN and tunnels section. it only had the ext vlan present and when I created the new network and new vlan (int_vlan) I needed to add it to that in order for it to connect to the VIPS
Hi Tim_Patrick ,
First don't rely on Ping/ICMP in your test , as F5 Bigip will reply to your Ping/ICMP packets if the Server B UP and will not forward traffic to server B itself.
I see you are trying to test reachability from Server A to Server B .
also you mentioned that VIP subnet 10.1.216.X can be reached from elsewhere. ( please test this by taking TCPdump on your Active F5 Bigip unit ) that Server A can reach well to bigip.
>> Second thing , you need to configure ( SNAT Auto map on Virtual server setting ( 10.1.216.113 ) ) as you said , Bigip is not the default gateway for Server B I guess.
Make sure Bigip can reach to servers which hosted by this ( VIP = 10.1.216.113 ) Ping this server from F5 bigip itself . to identify more where the issue exists.
Take this Pcap , and share the capture with me for further investigation if this available with you >>
tcpdump -nnnveti 0.0:nnnp host 10.1.228.27 -s0 -S -w /var/log/TEST_PCAP.pcapTake it through F5 bigip bash while trying to access server B VIP.
Please send your virtual server configuration as well to have a look.
Thanks 🙂
