Do you have an ARP cache problem?

Subject: Simple pinging problem
Date: Thu, 25 Oct 2001 14:14:53 -0400
Hello folks,
I connected a cross LAN cable between router's ethernet port and my
PC(win2K);
Problem is, I can NOT ping PC from router end, but I can ping the Router
from PC end.
router ip - 172.16.10.65/26 & PC's IP: 172.16.10.67/26
Router's Sh arp command shows my PC's MAC & IP address correctly(I can very
well see it from deb arp as well)
When I turned on, debug ip packet, I can see the packets are being sent to
ethernet interface, but it is not reaching my PC(as I don't see it in my
PC's
arp table) and nothing comes up in my sniffer.
When I ping from PC, I can see correct ip packet sequences from router's
debug
output.
I can even, telnet to the router from my PC via this cross cable, but again,
pinging from the telenet session still fails.
I do not see any output from deb ip icmp while I ping from router, but shows
usual output when I ping from PC.
Router do not have any special config and even I brought down all routing.
When I replace my PC with another router(with the same cross cable), it
works
fine.
I tried with different router models/ios and shows the same result.
Any hints!!!
