[squid-users] Very strange problem

Hi,

Our proxy/wccp setup has been working fine for a number of years now.

For some reason, it has stopped working today, without anything changed at
all.

What I have managed to find out from tcpdump and debug logs, is the
following :

12:17:43.601737 eth0 < gre-proto-0x883E (gre encap)
12:17:43.602104 eth0 < gre-proto-0x883E (gre encap)
12:17:43.611881 eth0 < gre-proto-0x883E (gre encap)
12:17:43.615020 eth0 < gre-proto-0x883E (gre encap)
12:17:43.642575 eth0 < gre-proto-0x883E (gre encap)

Tcpdump output above then i came across

12:13:47.042691 eth0 > dialup.sx.com.au > gw1.mel.satlink.net.au: icmp:
dialup.sx.com.au protocol 47 unreachable [tos 0xc0]

Why would it be saying unreachable on port 47?

I have my browser settings set to our proxy IP along with the port and it
just sits there, then times out.

Any ideas as to why this has suddenly happened?

No changes have been made.
