DNS query

have you configured default gateway on bigip?

 

 

by the way, isn't port number included in http host header?

 

 

e.g.

 

HTTP::header replace Host "soap.vendor.com:8080"

so i tried the following -

 

 

1.) I forgot the my DNS servers were in vlan 200 and that wasnt on the F5 and thus no self-ip.. i added that and still no luck..

 

2.) does it matter if i have dns servers setup on the f5? ‎- configuration-device-dns.. does that matter‎

 

3.) under network-arp-dynamic list, the dns servers have an entry there..

 

4.) i am able to ping the dns servers from the f5 from vlan 200 just fine...

can you post the virtual server and routing configuration?

 

 

b virtual ...name... list

 

b route list

ltm virtual vs_PAS_DEV {

 

destination 172.26.11.135:webcache

 

ip-protocol tcp

 

mask 255.255.255.255

 

profiles {

 

http { }

 

tcp-lan-optimized { }

 

}

 

rules {

 

irule_PAS_DEv

 

}

 

snat automap

 

vlans-disabled

 

}

 

ltm virtual vs_dns {

 

description "DNS pool"

 

destination 172.26.11.138:any

 

ip-protocol tcp

 

mask 255.255.255.255

 

pool dns_pool

 

profiles {

 

tcp-lan-optimized { }

 

}

 

snat automap

 

translate-port disabled

 

vlans-disabled

 

}

 

 

no static routes..

what is soap.vendor.com ip address? it is not in connected subnet, is it? if so, how can bigip reach it without having static route?

 

 

is there anything i missed??

So once the bigIP resolves the name to an address, I am going to need a default route our some kind of route to point that traffic out.. That makes sense.. I guess my problem is that the bigip isn't resolving my soap.vendor.com address.. :(

I guess my problem is that the bigip isn't resolving my soap.vendor.com address.. you may put some log command to see the RESOLV::lookup result.

 

 

by the way, in the irule, have you tried dns_pool ip address instead of 172.26.11.138?

so i tried the dns server directly instead of the vs_dns and that was able to resolve the name to an ip..

 

 

now i have to figure out why the request is being sent to the ip adn not IP/URI...

 

tmm info tmm[7386]: Rule /Common/irule_PAS_DEv: Sent request abc.mydomain.com:8080 /services/AssignGetInfo to 66.179.80.123

btw you have been very helpful!! to a newb like me this is a good learning experience.. thanks :)

tmm info tmm[7386]: Rule /Common/irule_PAS_DEv: Sent request abc.mydomain.com:8080 /services/AssignGetInfo to 66.179.80.123node_used is ip address, so i think what u see from log is expected.

 

 

if you run tcpdump, i think you could see the url.
