Load balancing issue

[Mabdelreheem]

Hello everyone,
I have an issue as the following :-
1. I have two adsl routers & pfserver with an external nic 4 port + 1 built in nic
2. I configure built in nic to lan
3. I  configure 2 ports from external nic to be wan1 , wan2
4. I configure load balancing between wan1 wan2 via create gateway group & rule
5. The problem is I can't reach routers from lan via url but i can ping both of them . And i can access internet normally!
6. I can reach routers from lan only when i disable load balace rule.
