AltostratusAdd a new data on the UDP payload
Hi,
I wish to find a way with an iRule to save a src_adress (client) at the end of the
UDP payload before SNAT. ( use RADIUS )
I implemented the irules according to :
...
Just to add to Dr. Teeth's post. You problem is that:
A) You don't set the length using UDP::payload length. The length is automatically determined by the amount of payload.
B) You can't replace 4 bytes starting at the end of the payload. You can insert 4 bytes at the end by using:
UDP::payload replace $udp_size 0 $Ip_src_adrAlso, if you do want to insert the IP address as a 32-bit (4 byte) number, you may want to search the forum for some examples of converting the IP address to a integer value.
