7.5.4.7
Confirmation of Relaying Network
It is possible that the communication has been interrupted because of an
impediment in the relaying network. For the correction procedure, refer to Section
7.5.1, “Communication cannot be done or communication is disconnected” on page
7-23.
If PPPoE is used, see Section 7.5.3, “Troubleshooting PPPoE Communication
Failures” on page 7-44 and if DHCP client is used, see Section 7.5.2.3,
“Troubleshooting DHCP Client Communication Failures” on page 7-41.
7.5.5
Domain resolution is not possible in DNS relay communication
Three factors that may produce communication troubles in the DNS relay (domain
solution is impossible) are as follows:
1. Error in setting the configuration defining information.
2. Impediments in this device.
3. Impediments and setting errors in the name server.
This chapter explains the impediment positions and the procedure for dividing the
causes thereof as described in the following flow.
(config)# show nat
nat {
outside_interface isp01 {
nat 192.168.1.0/24 auto;
};
inside_interface local01;
};
Confirm whether this interface name is
correct and whether or not an interface
name for the function, compatible with
NAT/NAPT, has been specified.
Confirm that this interface name is correct
and there is nothing missing.
