This is not a Wireguard specific issue and the two generally accepted solutions are NAT reflection (setting your edge router/firewall up in such a way as it translates internal packets correctly) or split horizon DNS (setting your internal DNS to return the private rather than public IP when connecting locally).
Both of these approaches have positives and negatives however their setup is out of scope for this document as everyone's network layout and equipment will be different.
## Maintaining local access to attached services
** Note: This is not a supported configuration by Linuxserver.io - use at your own risk.
When routing via Wireguard from another container using the `service` option in docker, you might lose access to the containers webUI locally. To avoid this, exclude the docker subnet from being routed via Wireguard by modifying your `wg0.conf` like so (modifying the subnets as you require):
```
[Interface]
PrivateKey = <private key>
Address = 9.8.7.6/32
DNS = 8.8.8.8
PostUp = DROUTE=$(ip route | grep default | awk '{print $3}'); HOMENET=192.168.0.0/16; HOMENET2=10.0.0.0/8; HOMENET3=172.16.0.0/12; ip route add $HOMENET3 via $DROUTE;ip route add $HOMENET2 via $DROUTE; ip route add $HOMENET via $DROUTE;iptables -I OUTPUT -d $HOMENET -j ACCEPT;iptables -A OUTPUT -d $HOMENET2 -j ACCEPT; iptables -A OUTPUT -d $HOMENET3 -j ACCEPT; iptables -A OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -m addrtype ! --dst-type LOCAL -j REJECT
