External Monitor + cURL + TFTP + Route Domains

Hi,

 

I'm trying to do a external monitor to check if a tftp server is alive.

 

During the development of the external monitor in a LAB, without route domains all works fine.

 

After applying in production with route domains it no longer works as expected.

 

The basic of the external monitor is:

curl --globoff --silent --max-time 5 -o /dev/null tftp://[10.xx.xx.180]:69/probef5

 

After a packet capture we see it is the LTM reply with a ICMP Port Unreachable

Even using tftp command in bash, the firt time run as expected, second in a row, it fail with timeout

 

[adm@LTM:/S1-green-P::Active:Changes Pending] run # rdexec 14 tftp -v 10.xx.xx.180 -c get probef5 Connected to 10.xx.xx.180 (10.xx.xx.180), port 69 getting from 10.xx.xx.180:probef5 to probef5 [netascii] Received 7 bytes in 0.0 seconds [1640 bit/s] [adm@LTM:/S1-green-P::Active:Changes Pending] run # rdexec 14 tftp -v 10.xx.xx.180 -c get probef5 Connected to 10.xx.xx.180 (10.xx.xx.180), port 69 getting from 10.xx.xx.180:probef5 to probef5 [netascii] Transfer timed out.

 

Any help would be appreciated.
