Edge client running on Macbook Pro 2016 with a touch bar interface cannot connect to VPN in a full tunneling configuration with 'Prohibit routing table modification' option selected. Edge client's svpn.log shows an error entry similar to 2017-05-18,13:55:17:000, 16637,16638,svpn, 1, , 870, CMacOSXRouteTable::UpdateIpForwardEntry2(), EXCEPTION - write failed, 22, Invalid argument.


VPN connection will fail.


This occurs when all of the following conditions are met: 1) Edge client is running on Macbook Pro that has the iBridge interface (e.g., one with the touch bar). 2) VPN is configured in full tunneling configuration 3) Mac OS X version is v10.12.5. Note: You can find the interface on the Macbook Pro in the Network Utility under the Info tab.


Use one of the following workarounds: - Disable 'Prohibit Routing table change' in the network access configuration. - Enable 'Allow access to local subnets'. - Enable a split tunneling configuration.
