I can't configure rhel8 server to work as local gateway.
net.ipv4.ip_forward = 1 is enabled, but clients of this gw can't acess external network
I also applied commands which works well on rhel7:
server have 2 nic
int1 : 192.168.1.2 and ext : 10.0.1.2, and i try configure forwarding with firewalld:
firewall-cmd --direct --permanent --add-rule ipv4 nat POSTROUTING 0 -o ext1 -j MASQUERADE; firewall-cmd --direct --permanent --add-rule ipv4 filter FORWARD 0 -i int1 -o ext1 -j ACCEPT; firewall-cmd --direct --permanent --add-rule ipv4 filter FORWARD 0 -i ext1 -o int1 -m state --state RELATED,ESTABLISHED -j ACCEPT;
on client servers:
ip route add default via 192.168.1.2
But, like I said, it's work fine only with rhel7 gateway server. With rhel8 i get this
[root@client1 ~]# traceroute -T -p 443 access.redhat.com traceroute to 220.127.116.11 (18.104.22.168), 30 hops max, 60 byte packets 1 _gateway (192.168.1.2) 1.435 ms 0.946 ms 6.314 ms 2 _gateway (192.168.1.2) 6.292 ms !X 6.264 ms !X 6.235 ms !X
also i tried to disable NetworkManager and install legacy network-scripts but without success.
please explain to me where i am wrong.
