[c-nsp] DSCP / NAT

[Darryl Dunkin]

Correct, it should just go straight through, NAT translates the
address/port only. It should not touch the rest of the packet unless
otherwise configured.

I thought that was the default action for most NATing devices?  I'm
pretty sure the 12.4 Cisco devices I've used all do that.

Hi folks.

 

This is probably a dumb question ;)  Is there any way for a packet that
hits
NAT to have it's DSCP bits honored?

 

For example:

 

Interface FastE0 - public IP - ip nat outside

 

Interface FastE1 - private IP - ip nat inside

 

Device attached to FastE1 sends DSCP 46 - looking for a way for that to
pass
through without remarking it on FastE0 - is there such a method?

 

Thanks,

Paul
