There is lots of packetloss. Also, it is obvious from this dump that
lan_router is sending both over eth1 and eth2, but that the wan router is
only receiving on eth2, and not on eth1, or that your dump failed.

    lan_router_eth1         10-Oct-2000 16:16    73k  
    lan_router_eth2         10-Oct-2000 16:16    73k  
    lan_router_teql0        10-Oct-2000 16:16    42k  
    wan_router_eth1         10-Oct-2000 16:15     1k
    wan_router_eth2         10-Oct-2000 16:15    46k
    wan_router_teql0        10-Oct-2000 16:15   146k
  
lan_router_eth[12] carry ftp data, teql0 carries acknowledgements, and lots
of them are duplicate or triplicate, indicating packetloss and resends.

wan_router_eth1 receives almost nothing, while wan_router_eth2 is sees the
same the ACKs seen by teql0 on the lan_router, also duplicate.

wan_router_teql0 sees packets also seen by lan_router_eth1 and eth2, and
they are alternatingly from eth1 and eth2, which is as it should be.

10.2.18.2 is telling ftp2.citynet.nu that is is missing packets, so it
appears that data is getting lost on the other way. I'm not sure if this is
related to TEQL.

I'm interested in knowing what you make of the nearly empty wan_router_eth1
file.
