You may give little more info.

"iptables -L -v" or
"ipchains -L -v" (whatever you use)
"ip route"
"arp"

"mii-tool -v <INT>"
"ifconfig <INT>"

"free -t"
"dmesg"

How is your gw connected to the local network (switch, hub, x-over)?

Problem: while transfering data through a dual-hosted-nat gateway,
bandwidth differs about factor 5..10 instead of direct connections.

1. scenarion: single machine
- machine directly connected to the internet
- transfering 10MB of data within 10 seconds

so far, so good!

2. scenario: gateway
- two lan-interfaces (WAN: 10Mbit, LAN: 100Mbit)
- transfering 10MB of data through the gateway within 122 seconds ?!?

How do i have to configure both lan-interfaces for best throughput?
When i look at the traffic-statistiks, there is a gap of 200ms silence
followed by 300ms transmission. Why?

Any help or hints are very welcome!

Greetings
Bernhard
