Hi,

In my configuration i have connected Servers through an DMZ Interface with official IP's. Case: w/o proxyarp: we are connected, but very small amount of traffic goes through the ISP's gate. w/ proxyarp: all things go fine.... after a call to the ISP we have cleared, that the equipement from the ISP needs proxyarp for all the machines are connected with public ip's and he have no chance to change it (so says ISP's suporter regardless if it really true). the resulted behavior w/o proxyarp was the described in the original post. In my Case(!). ACK rrd-graphs have nothing to do with this behaviour..... greetings michael -- === m i c h a e l - s c h u h . n e t === Michael Schuh Postfach 10 21 52 66021 Saarbrücken phone: 0681/8319664 mobil: 0177/9738644 @: m i c h a e l . s c h u h @ g m a i l . c o m === Ust-ID: DE251072318 ===
