it's possible to rewrite mac address?

but the problem is the server's IP were not reachable. it is not reachable because incoming packet goes from external client, router and then server but return packet would go from the server to bigip and i guess bigip would drop it. not sure if stateless virtual server (handle return traffic) would help. anyway, i think specific virtual server (ip or port) could work.

Hi NItass,

 

 

Thank you for your response. i have the following servers:

 

 

202.126.41.X

 

202.126.45.X

 

202.126.34.X

 

 

Would you mind giving me example of VS to be configured in this case?

Hi Nitass,

 

 

Also, i have read some regarding proxy arp and vlan-group creation.do i need to?

can you try something like this?

root@ve1110(Active)(/Common)(tmos) list ltm virtual vs_wildcard_forwarding
ltm virtual vs_wildcard_forwarding {
    destination 0.0.0.0:0
    ip-forward
    mask any
    profiles {
        my_route_friendly_fastl4 { }
    }
    translate-address disabled
    translate-port disabled
    vlans-disabled
}
root@ve1110(Active)(/Common)(tmos) list ltm profile fastl4 my_route_friendly_fastl4
ltm profile fastl4 my_route_friendly_fastl4 {
    app-service none
    defaults-from fastL4
    loose-close enabled
    loose-initialization enabled
    reset-on-timeout disabled
}

Hi Nitass,

 

 

Thank you so much. It seemed to be working on our lab. We will schedule this since we need window time to implement this action item.Also, do we really need to disable reset-on-timeout? also, why do we need to enable loose-close and loose-initialization?

why do we need to enable loose-close and loose-initialization?bigip maintains connection state. since incoming packet does not pass through bigip but return packet does, without enabling loose initiation bigip would drop return packet.

 

 

do we really need to disable reset-on-timeout? i think it might work even enabling reset-on-timeout. anyway, the sol emulates stateless ip routing, so i think it does not want bigip to interfere connection (i.e. by resetting).

Hi Nitass,

 

 

Thank you so much.I'll be posting the result once done.

 

 

Thanks!

Hi Nitass,

 

 

 

The configuration you suggested works on live environment. Thank you so much!
