I have tried to find the solution but to no avail. Have tried to do a ping from a remote PC to a printer, but seems like pinging with 1500 makes it timed out.
Is there any reasons for this?
Thanks in advanced.
The command that Sundar is talking about works for TCP traffic but not for ICMP. So it will have no effect on your ping.
This command would cause the MTU negotiated by the TCP client/server to use 1450. The router would transparently lower the MTU to 1450 bytes during the TCP negotiation between the TCP client and server. I have found this command to be effective to address MTU problems.
Here's a couple of documents that can help your understanding.
