while setting up vlans on a linksys SRW2024 gig-E switch, i am encountering stalling FTP transfers from one vlan to another. the topology is as follows:
######################## # SRW2024 switch # ###T####T######U2###U3## | | | | | | | | GW#1--GW#2 ftpsvr ftpclient where U2 denotes a port that is "untagged w/ vlan ID 2", U3 => "untagged with w/ vlan ID 3", GW machines are CARPed and their ports are tagged on vlan 2 and 3, and the GW machines route both vlan 2 and 3 (i.e. clients on vlans 2 and 3 have the GW CARP IPs listed as their gateway IPs). since the GW machines are the gateway between the vlans, a connection to ftpsvr from ftpclient passes through the GW machines. the PF rules for GW are totally open, with only pass on vlan0 keep state pass on vlan1 keep state in place for testing. ftpclient can successfully ping, connect to ftpsvr, and list files, but when a transfer begins it stalls after moving ~66 KB of data. FTP works fine between hosts on the same vlan using untagged ports. i'm confident others must have encountered this same problem when setting up vlans. clues are appreciated. cheers, jake
