- Content Server always sees client’s IP address
- Content Server always sees Proxy Server’s IP address
- Content Server sees client’s IP address, if the proxy is configured as transparent proxy
- The IP address seen by the Content Server depends on the Proxy SG configuration parameter reflect-client-ip
-
Which statement is true about a ProxySG with factory settings:
- To get network access, initial setup is necessary — ProxySG does not have an IP address until then
- Unconfigured ProxySG responds to some of the pre-built IP addresses, which are contained in the private IP address ranges 10.0.0.0/255.0.0.0 and 172.16.0.0/255.240.0.0 and 192.168.0.0/255.255.0.0 .
- Unconfigured ProxySG tries to obtain IP address from a DHCP server
- Unconfigured ProxySG sends RARP request to look up its IP address from the MAC address of its network interface card. If it cannot get a valid IP address, initial setup is required.
-
