Hi.
I'm trying to set up a BGP configuration between a Cisco router and Firewall. I made a lab using a firewall virtualized and GNS3 and I could make it work as well. But when I tried to do it in physical appliances, I got an error in Cisco that I cannot udnerstand why this is happening.
Here is the debug log from TCP.

It's saying congestion window changes... both MSS configuration are set to default... does anybody see that before?
Thanks !
