IPSEC VPN Multiple Lan Subnet from Sophos XGS to CISCO: only one subnet works at a time

Hi,

we're  experiencing a problem with Ipsec Vpn (site2site) from Sophos to Cisco.

In the Ipsec tunnel we have two subnet (subnet1 e subnet2) at sophos vpn side and one subnet (subnet3) in the remote site managed by cisco.

It seems that only on subnet at time works but not both.

When ipsec tunnel is up only traffic from subnet1 can reach subnet3. If I remove subnet1 from the ipsec tunnel subnet2 can reach subnet3 on the other side.

Is there a way to by bypass this problem?

Thanks in advance
