Wireguard no handshake on iOS

Sat Jul 13, 2024 8:35 pm

I created a simple wireguard configuration for 2 peers (Android phone and iPad) the Android phone works without an issue but the iPad doesn't even handshake. I used qr code to transfer configuration to both and they have same configuration other than ip and keys, I even added ipads configuration to my phone and it worked fine. Below is my config, it's mostly stock, I'm not sure if it can be an issue on the router side, sounds more like an ios problem but maybe I missed something.
Code: Select all
/interface bridge

where is your input firewall rule that accepts udp requests on wireguard port 13231?
also include wireguard interface in LAN interface list for seamless firewall navigation

I assume the
Code: Select all
/ip firewall filter
add action=accept chain=input comment=\
    "defconf: accept established,related,untracked" connection-state=\
    established,related,untracked
rule must be accepting it, since Android phone connects just fine from the internet.
Also I ran the sniffer to see what's going on and with phone there is a traffic on 13231 udp as expected, however for some reason iPad seems to only talk to google dns (8.8.8.8 ) and sends nothing on the 13231

Greetings. You're missing the wireguard interface from the interface member list. Missing the biggest part, the firewall rule in the input chain. Wireguard peers might need to be adjusted. Start with the first 2. Lastly, if you can't connect, adjust peers. Hope this helps

Code: Select all
/interface list member
add interface=wireguard list=LAN

## Place after the input chain rule: "defconf: accept to local loopback (for CAPsMAN)"
/ip firewall filter
add action=accept chain=input comment="allow wireguard handshake" dst-port=13231 protocol=udp

## Might need to adjust your peers.
/interface wireguard peers
add allowed-address=192.168.100.4/32 interface=wireguard name=KrzysPixel public-key="6xJIhMljwYHM3VCe8qyvMd/HRFXROd7K8oTaZqe2xHc="

Concur with previous posters.
If your android is connecting its using BTH not regular wireguard setting Which is only required if you dont have a public IP.

For client devices allowed IPs, you need either,
BOTH the subnet of wireguard and the subnet(s) you need to access { 192.168.100.0/24,192.168.1.0/24 }
OR
If you required internet then 0.0.0.0/0 which includes both items above! { 0.0.0.0/0 }

Recommend NOT to use BTH and as recommended
a. put in the input chain rule.
b. add wireguard to the LAN interface
c. change your NAT RULE TO:
add action=masquerade chain=srcnat comment=hairpin dst-address=192.168.1.0/24 src-address=192.168.1.0/24

As noted your Router wireguard allowed IPs should look like.
/interface wireguard peers
add allowed-address=192.168.100.4/32 interface=wireguard name=KrzysPixel public-key="#####"
add allowed-address=192.168.100.3/32 interface=wireguard name=ipad public-key="***"

DISABLE UPNP, it should NOT be required.
REMOVE All IPV6 firewall rules and lists if the IPV6 is disable.

Set to NONE:
/tool mac-server
set allowed-interface-list=NONE

Finally change your forward chain rules as follows:
REMOVE DEFAULT RULE AND REPLACE
add action=drop chain=forward comment=\
"defconf: drop all from WAN not DSTNATed" connection-nat-state=!dstnat \
connection-state=new in-interface-list=WAN

With:
add action=accept chain=forward comment="internet traffic" in-interface-list=LAN out-interface-list=WAN
add action=accept chain=forward comment="port forwarding" connection-nat-state=dstnat
add action=drop chain=forward comment="drop all else"
