Hmmz the fact is that the IP_QUERYING_SERVER is the random ip which connects to the server or sends a query for it. Hmmz mayby the problem is with my router that the provider said me to use GATEWAY_IP as my gateway but redirects it to the another ip NEW_GATEWAY_ADDRESS, mayby if i'll use that new gateways ip, it will stop that messages? But in that case i think i wont have the internet connection in my server anymore? On 29 Nov 2003 13:42:47 +0100 Dirk Geschke <Dirk () geschke-online de> wrote:
Hi Paulius,Hmmz what is wrong here i get a lot of messages like this: [**] ICMP redirect host [**] 11/28-04:42:15.156908 GATEWAY_IP -> MY_IP ICMP TTL:255 TOS:0xC0 ID:8567 IpLen:20 DgmLen:88 Type:5 Code:1 REDIRECT HOST NEW GW: NEW_GATEWAY_ADDRESS ** ORIGINAL DATAGRAM DUMP: MY_IP:80 -> IP_QUERYING_SERVER:1370 TCP TTL:64 TOS:0x0 ID:62447 IpLen:20 DgmLen:60 DF ***A**S* Seq: 0x4882360D Ack: 0x85F021AF Win: 0xE000 TcpLen: 40 ** END OF DUMP How to solve this, to not receive thousands messages like this? And this is problem in my server or in my router?without knowledge of your network it is a little bit difficult. But I think your server has a wrong routing entry to IP_QUERYING SERVER. So probably the server sends all traffic to your GATEWAY_IP. This gateway informs your server about the wrong route. So simply check your routing table. Best regards Dirk
