Communications problems between servers
Hi,
We have some problems with the comunications of some server. The situation is below:
- Server A on VLAN 1 with IP 192.168.1.1/24
- Server B on VLAN 1 with IP 192.168.1.3/24
- Server C on VLAN 1 with IP 192.168.1.5/24
- Virtual Server on VLAN 2 with IP 192.168.3.2/24 (its nodes are servers A and B)
The service is over http and https, and we are not using SNAT.
When clients from Internet try to connect to the Service there is no problem; but when server C ask for virtual server service, the connections never reach the server A or B. We just have this problem with connections over servers are in the same VLAN.
If we do a tcpdump we can see:
12:00:15.139092 IP 192.162.1.5.dyna-lm > 192.162.3.2.http: S 1702227370:1702227370(0) win 65535 <mss 1460,nop,nop,sackOK>
But the connection seems it doesn´t go out from the BIG-IP since in the servers A and B we cannot see any connection from server C or Virtual Server.
Any idea? Could you help me?
Thanks Regards
