Vlans + subinterfaces on RH9.0
 

I have config on the hosting server like this

obviously port on the switch in trunk mode


everything works except uploading files via ftp or sftp it "stalles". In
fact very small files can be uploaded (up to about 50K). SSH itself
works just fine, and sftp commands work just fine (like pwd or ls or cd, etc.)

about the same config on another box works great including uploads. In
fact other box serves in to two vlans on completely different subnets
(internal and external) with two different gateways.

For those how will offer subinterfaces: It is running on those now, but
I ran out of IPs in this subnet so I have to add vlan support.


Any ideas why transfers does not work?


For those who interested below is the config from the box that works
just fine:

I even tried to add 3 subinterfaces on vlan800 interface, still works. I am clueless :Pengy:

Nothing in dmesg or any other logs, sniffing with ethereal shows that no replies are coming back, and uploading host is trying to retransmit all the time

Thanks,
Any help is deeply appreciated.
