Basic question, but one that has me confused:
I’ve been debugging IP ICMP on one of my routers: router2, router1 is the internet gateway and router2 sits between router1 and my firewall, i.e. Internet>Router1>router2>firewall>LAN
the Firewalls only gateway is router2 and router2’s only gateway is router1.
I have been running a ping from the internet to the firewall, and another back out from the firewall to the internet and been debugging traffic on router2.
router2 shows traffic thatsays:
ICMP: redirect sent to for dest , use GW
Does this debug show incoming pings from the internet?? I.e. is it showing that it is redirecting traffic to for , if so why does it mention ?
basically I want to know what ‘redirect sent to’, ‘for dest’ and ‘use gw’ mean in the ICMP debug?
