XG SSL Site-to-Site / Openwrt OS -Raspbian OS

 Hi,

I'm trying to make a site-to-site tunnel using one Sophos XG and a remote raspberry whit Openwrt or Raspbian OS

this is remote config:

client
proto udp
dev tun
ca server_OFFICE-ca.crt
cert server_OFFICE.crt
key server_OFFICE.key
remote my.office.com 443
auth-user-pass server_OFFICE.auth
auth SHA512
cipher AES-256-CBC
user nobody
group nogroup
verb 2
mute 20
keepalive 10 120
comp-lzo
persist-key
persist-tun
float
resolv-retry infinite
nobindcomp-lzo no
route-delay 4
verb 3
reneg-sec 0

works, tun0 came up, but remote can't add a route to my office lan

Thu Aug 22 20:03:57 2019 /sbin/ip addr add dev tun0 172.22.198.193/26 broadcast 172.22.198.255
Thu Aug 22 20:04:01 2019 /sbin/ip route add 172.22.201.0/24 via 172.22.198.192
Error: Nexthop has invalid gateway.

If I try the same config on my windows notebook whi openvpn community client and works like a charm
