Unable to print using L2L Tunnel

Hi All,

I have a situation where site A accesses a program at site B though a L2L tunnel

The tunnel is up and functioning and the users can access and use the program with no issues but when they try to print from the program to a printer at site A it does not print.  The admin at site B can see the print jobs in the queue at his site. He can also ping the printer from site B

site A 192.168.0.X

site B 192.168.10.X

printer at site A is

Note: the issue coincides with the addition on another L2L Tunnel that I created and had to NAT it to a different IP for that tunnel

I did back out this changes and the issue with the printing still happened so I am not sure if it was the cause

Try lowering the MSS value on your LAN interface --> ip tcp adjust-mss 1260

OR, if it's an ASA firewall --> sysopt connection tcpmss 1260

Hope that helps.

Re: Unable to print using L2L Tunnel

I adjusted the setting per your suggestion:

sysopt connection tcpmss 1260

But still no joy.  Do we need to reestablish the tunnel or should the change be immediate?

You would need to re-establish the TCP connection from your PC towards the printer.
