VIP fails Telnet but responds to ICMP
F5A telnet 10.45.2.10 80 Trying 10.45.2.10...
telnet: connect to address 10.45.2.10: No route to host telnet:
Unable to connect to remote host: No route to host
F5A ping 10.45.2.10
PING 10.45.2.10 (10.45.2.10 ) 56(84) bytes of data.

virtual vs_80 { translate address disable translate service disable pool pool80 destination 10.45.2.10:www ip protocol tcp persist persist80 profiles fastl4_80 {} vlans 80 enable }
Pool members are showing as - inactive down and not responding to telnet on port 80.
However, memebrs are pinging from F5.
Any ideas..what route is missing here when VIP is pinging?
- El_JefeNimbostratusIf the pool members are down, the monitor is marking them as down. The servers are there, and therefore respond to pings from the LTM. What kind of monitor are you using?
- nitassEmployeevirtual vs_80 { translate address disable translate service disable pool pool80 destination 10.45.2.10:www ip protocol tcp persist persist80 profiles fastl4_80 {} vlans 80 enable } what is pool80 member?
- genseek_32178Nimbostratusyes, translate address and server are disabled.
- El_JefeNimbostratusOK, first off, if you are using a monitor for web servers listening on port 80, use a custom HTTP monitor to test the servers. I usually start with a GET /\r\n\r\n as the monitor and wait for a 200 OK response. You can get more specific, but that is just a baseline. Use a tool like fiddler or HTTPWatch to get more elaborate.
- nitassEmployeeyes, translate address and server are disabled. translate address should not be disabled since virtual server address and pool member address are different.
- genseek_32178Nimbostratuswhen VIP and pool members are on diffrent network, is it always to enable translate address and server?
- nitassEmployeewhen VIP and pool members are on diffrent network, is it always to enable translate address and server?yes if pool member is final destination.
- nitassEmployeeoh i see it is npath/direct server return configuration.
- genseek_32178Nimbostratusyes, subnet is /24.
- nitassEmployeeyou mean..client --->VIP--> Pool Member...if this is working?yes
