Mi?rcoles, 26 de Octubre de 2005 Hello everybody, I have e little problem. In this moment i have one corebuilder 9000 an one firewall with debian sarge running a kernel version 2.6.12 with the vlan package (stable) version 1.8-1. the ethernet port is: Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] (rev 08) I have no problems when i create the vlans and ping between the diferent vlan. I have a server on linux over a gigabit ethernet (SC conection) and my firewall is over one 100 BaseT tagged conection (the pro100). For my firewall when i want to conect to this server i use the vlan 99. i can conect to this server with ssh protocol, but when a list a directory or try to open with vim an archive the ssh hang up and i loose de conetion. at the first i think that is a problem of flowcontrol becouse my firewall is with a poor conection than the server, but if i unconfigure the vlan suport and connect the firewall to the corebuilder on untagged port i don't have problem. can you guide me with the problem please? It is a problem of MTU? (not , for me) Thanks in advance. Diego S. Alonso
