Looks like you are having issue with TFTP. With recent firewalld, you have to have some mechanism for inter-zone traffic. I’m not sure if the one on CentOS 7 is covered. Also, you missed to show the zones of your interfaces.

I have these on my setup where the storage server has 3 interfaces serving diskless clients via iscsi:

For my external zone:

[root@san ~]# ip -4 addr ls xenbr0
6: xenbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    inet 192.168.0.33/27 brd 192.168.0.63 scope global dynamic noprefixroute xenbr0
       valid_lft 3181sec preferred_lft 3181sec
[root@san ~]# 
[root@san ~]# firewall-cmd --get-zone-of-interface=xenbr0
external
[root@san ~]# firewall-cmd --zone=external --list-services
dhcp http https iscsi-target samba ssh tftp

And this is my internal zone

[root@san ~]# ip -4 addr ls xenbr10
7: xenbr10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP group default qlen 1000
    inet 192.168.10.1/24 brd 192.168.10.255 scope global noprefixroute xenbr10
       valid_lft forever preferred_lft forever
[root@san ~]# 
[root@san ~]# firewall-cmd --get-zone-of-interface=xenbr10
internal
[root@san ~]# firewall-cmd --zone=internal --list-services
dhcp http https iscsi-target postgresql samba ssh tftp

I have these firewalld rule to enable the inter-zone traffic:

 [root@san ~]# cat firewalld.txt
firewall-cmd --new-policy NAT_int_to_ext --permanent
firewall-cmd --permanent --policy NAT_int_to_ext --add-ingress-zone internal
firewall-cmd --permanent --policy NAT_int_to_ext --add-egress-zone external
firewall-cmd --permanent --policy NAT_int_to_ext --set-target ACCEPT

Finally, I test things out from one of my vms and tried to can grab a file over tftp

user@debian:~$ ip -4 addr ls virbr0
5: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP group default qlen 1000
    inet 192.168.10.15/24 brd 192.168.10.255 scope global dynamic virbr0
       valid_lft 2111sec preferred_lft 2111sec
user@debian:~$ 
user@debian:~$ tftp 192.168.10.1 -vc get ipxe.d/roms/undionly.kpxe

@FrSainCpel
It appears to me that your block ‘:retry_left’ will cause an infinite loop if it failed to boot.

The line ‘set keep-san 1’ is no longer necessary when sanhooking (or sanboot) is used .

As you are setting up an static IP, you’d need to do an ‘ifopen net0’ first’. With dhcp, it does that for you.

I’d suggest put the net0/ip first before the netmask.

Lastly, @george1421 is correct, you’d need

set net0/gateway 0.0.0.0
