masquerade | CUBA Platform UI Testing Library | Testing library

After trying many solutions finally I found the answer. My ethernet interface called ens160 so for IP masquerading I should use this:

Flannel does not support NFT, and since you are using CentOS 8, you can't fallback to iptables.
Your best bet in this situation would be to switch to Calico.
You have to update Calico DaemonSet with:

Are you still having this error? I managed to fix this by downgrading windows kube-proxy to at least 1.20.0. There must be some missing config or bug for 1.21.0.

As already mentioned in the comments debian buster uses nftables backed instead of iptables:

NOTE: iptables is being replaced by nftables starting with Debian Buster - reference here

Unfortunately the nftables are not compatible at this moment with kubernetes.

In Linux, nftables is available as a modern replacement for the kernel’s iptables subsystem. The iptables tooling can act as a compatibility layer, behaving like iptables but actually configuring nftables. This nftables backend is not compatible with the current kubeadm packages: it causes duplicated firewall rules and breaks kube-proxy. You could try to switch to legacy option like described here but I'm not sure about this solution as I don't have a way to test it with your Os. I solved similar case with debian with this here.

Alternative way would to switch to Calico which actually supports nftbacked with FELIX_IPTABLESBACKEND. This parameter controls which variant of iptables binary Felix uses. Set this to Auto for auto detection of the backend. If a specific backend is needed then use NFT for hosts using a netfilter backend or Legacy for others. [Default: Auto].

When installing calico with containerd please also have a look a this case.

Please confirm that you enabled port forwarding on both sides.

• Here shows how to enable port forwarding on GCP
• To enable it under the OS please run the followed commands as root:

# echo 1> / proc / sys / net / ipv4 / ip_forward

In order the forwarding bit remains active we will have to modify the file /etc/sysctl.conf and we will uncomment the line

# net.ipv4.ip_forward = 1

Uncomment the line and reload

sudo sysctl -p

Now you can run your commands

sudo iptables -t nat -A PREROUTING -p tcp --dport xx -j DNAT --to-destination XXX.XXX.XXX.XXX:xxxx

First, I took a subset of the data to make there be one observation for each bar I want to plot and label with an important_label. It seems like the data set in question has 6 identical copies of each line when we just look at the variables that feed into the plot: h.names, names, and value.

You can see this replication by replacing in the OP geom_col(position = "dodge") + with geom_jitter() + or by running df %>% count(h.names, names, value).

Here is how you would add the text you had in your original question to each bar. Please note that I moved data = df, mapping = aes(x = names, y = value up into the ggplot() aesthetic where it will be applied to each layer in the plot. Next, used case_when from the dplyr package to add the bar plot labels as a new column to df. After that you pass in the new column into geom_text like so geom_text(aes(label = bar_labels, hjust = 0)) to apply the labels on the tip of each bar.

The wg0 interface is already up. To restart it, run wg-quick down wg0 and then wg-quick up wg0 again.

WireGuard is not running as a separate process listening on port 7456, so you won't see anything for it with lsof. Try a command like ss -ptuna | grep 7456 instead. Or run wg show to get a pretty display from WireGuard itself.

Also, you probably want to use /32 in your AllowedIPs = 10.0.0.3/24 setting, instead of /24 (to route only a single address, instead a block of addresses, to that peer).

Try removing the query string 403 lines.

It could work locally if you don't have mod alias enabled as those lines will be skipped.
