TFTP connection over NAT broken if external server is used -> fixed in SVN

Description

Hello,

I've tried to use an external TFTP server during PXE boot from a virtual host (--nattftpserver1 "..."). NAT is configured for this host with its default network settings (10.0.2.0/24). The public IP of the hosting PC is a valid global address.

When PXE boot tries to establish a connection to the server, its packets seem to be intercepted by the internal TFTP server and they are not forwarded to destination. Nictracing claims that external server has sent an ERROR ENOTFOUND "File not found", but in reality no packet is sent to this server over the network.

Precision: it happens if the server address is xxx.xxx.xxx.4 .

Workaround: Change the tftp server IP address and put "--nataliasmode1 proxyonly"
