Running the tcpdump on warp interface in VSX Gateway

Jump to solution

Hi ,

If i will run the tcpdump in warp interface (which is source interface ) will i get the echo request and echo reply (Generating ping packet) ? 

For example if source server a.b.c.d routing  through  wrp220 interface  and destination : e.f.g.h is directly connected showing through eth3-03 interface and if i run tcpdump in VS5 as below 

 

tcpdump -i wrp220 -nn host a.b.c.d and host e.f.g.h . Should i get the echo request and echo reply both the packet with this command ? 

 Or 

if i run this command through "any" interface then it will show as below 

tcpdump -i any  -nn host a.b.c.d and host e.f.g.h.

Indeed the best bet prior USFW is to use physical interfaces instead of wrp - you either will get nothing or one way traffic only.

But USFW version seems to work also on wrp links

Not sure if this is still true, but in the past, you would get unexpected behavior when tcpdumping the warp interface.
Best to do the relevant physical interface instead.
