routing problem

[mr_red]

Hi guys,

I have a small problem here with my routing table.

I need to access a remote server (192.20.20.20) using ip 172.20.100.101 (lan5000). Here are the routing rules on my server :

# netstat -inw
Name              Mtu        Network         Address         
lo0               32808      127.0.0.0       127.0.0.1
lan5000:801       1500       172.20.100.0    172.20.100.131
lan5000:802       1500       172.20.100.0    172.20.100.121
lan5000           1500       172.20.100.0    172.20.100.101

# netstat -nrv
Routing tables

192.168.254.0/255.255.255.0     172.20.100.254     UG    0    lan5000    1500
127.0.0.0/255.0.0.0             127.0.0.1          U     0    lo0       32808

default/0.0.0.0                 172.20.100.254     UG    0    lan5000:802  1500
default/0.0.0.0                 172.20.100.254     UG    0    lan5000:801  1500

When I try to telnet the remote server i found that packets are using ip 172.20.100.131 (lan5000:801)

# telnet 192.20.20.20 1107

# tcpdump -ni 3 | grep "192.20.20.20"
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lan5000, link-type EN10MB (Ethernet), capture size 65535 bytes
09:21:19.707496 IP 172.20.100.131.20651 > 192.20.20.20.1107: Flags [S], seq 3830382809, win 32768, options [mss 1460,wscale 0,nop], length 0

(I'm using telnet because ping is blocked)

Can someone help me to figure out the source of the problem because I don't see what i'm missing. (it's hpux 11.31)

Thank you!
