Hello, I'm having a problem with BLF in some cases, and I found that the length of the username was a factor in whether the lamps worked or not. When I did some packet captures, I found that problem packets were 1500 bytes or so. Since the endpoint is on a DSL line that has an MTU of 1460, the packet doesn't fit. I'm already using compressed headers. Is there a way to reduce the packet size more, or is there another solution? I will include an example below: Note that my IP address and domain substutions may change the packet size a little, but the point is the same. Thanks!
